MRI scanner: Overview, Uses and Top Manufacturer Company

Introduction

An MRI scanner (Magnetic Resonance Imaging scanner) is a high-complexity imaging medical device that uses strong magnetic fields and radiofrequency (RF) energy to create detailed pictures of internal anatomy—without using ionizing radiation (unlike X-ray or CT). It is a cornerstone of modern diagnostics because it can characterize soft tissues, detect disease patterns, and support treatment planning across neurology, orthopedics, oncology, cardiology, and more.

For learners, MRI can feel “black box” because image contrast depends on physics, pulse sequences, and patient factors. For hospital leaders and biomedical teams, MRI is also one of the most operationally demanding pieces of hospital equipment: it requires careful site planning, strict safety controls, specialized staffing, and long-term service support.

This article explains what an MRI scanner is, when it’s typically used (and when it may not be suitable), basic operation, patient safety, output interpretation, troubleshooting, cleaning and infection control, and a practical global market overview to support clinical training and procurement decisions.

What is MRI scanner and why do we use it?

Definition and purpose

An MRI scanner is clinical device designed to generate cross-sectional images (and sometimes functional or quantitative maps) of the body. Its main purpose is to provide high-contrast visualization of soft tissues—brain, spinal cord, ligaments, cartilage, marrow, pelvic organs, and many tumors—often with better tissue differentiation than modalities such as ultrasound or CT, depending on the clinical question.

MRI is used to:

• Detect or characterize suspected pathology
• Stage disease and plan interventions (surgery, radiation, medical therapy)
• Monitor treatment response or progression
• Guide selected procedures in specialized settings (varies by facility)

Common clinical settings

MRI scanners are found in:

• Radiology departments in tertiary hospitals and academic medical centers
• Dedicated outpatient imaging centers
• Emergency-adjacent imaging suites (where patient stability and workflow allow)
• Specialty programs (stroke, epilepsy, musculoskeletal, oncology, cardiac imaging)
• Research environments (advanced methods, subject to local approvals)

Access and throughput vary widely by region and resource setting. Some facilities run MRI primarily as scheduled outpatient service, while others integrate MRI into urgent inpatient pathways.

Key benefits for patient care and workflow

From a clinical perspective, MRI is valued for:

• Soft-tissue contrast: Strong capability to differentiate tissues that can look similar on CT.
• Multi-planar imaging: Images can be acquired in multiple planes (axial, sagittal, coronal) without moving the patient.
• Functional and vascular options: Techniques like diffusion-weighted imaging (DWI), perfusion methods, and MR angiography can add physiologic context (availability varies by manufacturer and software licenses).
• No ionizing radiation: Helpful for patients needing serial follow-up imaging, when appropriate for the clinical question.

From an operations perspective, benefits can include:

• Broad service line utility: One MRI scanner may support multiple departments (neuro, MSK, oncology, pediatrics).
• Protocol flexibility: Protocols can be tailored to the question, time available, and patient tolerance.
• Digital integration: DICOM (Digital Imaging and Communications in Medicine) output integrates with PACS (Picture Archiving and Communication System) and radiology workflows.

Trade-offs are real: MRI exams can be longer than CT, are sensitive to motion, and require extensive safety screening.

How MRI works (plain-language mechanism)

MRI leverages three main components:

1. A strong static magnetic field (B0)
   This aligns hydrogen nuclei (protons) in the body. Because the magnetic field is very strong, ferromagnetic objects can become dangerous projectiles, and some implants/devices may be affected.

2. RF pulses
   The scanner transmits RF energy at a frequency that interacts with the aligned protons. When the RF pulse stops, the protons relax back toward equilibrium and emit signals.

3. Gradient magnetic fields
   Gradient coils vary the magnetic field in space. This allows the scanner to localize signals and reconstruct an image.

Computers reconstruct the detected signals into images. The “look” of an MRI image depends on the pulse sequence and timing parameters, which influence how different tissues appear.

How medical students encounter MRI in training

Medical students and trainees typically meet the MRI scanner in three ways:

• Ordering and indications: Learning what MRI can answer better than other modalities.
• Safety and patient preparation: Understanding why MRI screening is strict and why certain items are prohibited.
• Basic image interpretation: Recognizing core sequences (e.g., T1-weighted, T2-weighted, FLAIR, diffusion) and common artifacts.

In many programs, early exposure focuses on clinical reasoning (“What question am I asking?”), while later training adds operational detail, safety culture, and image-quality concepts.

When should I use MRI scanner (and when should I not)?

Appropriate use cases (general)

Whether an MRI scanner is appropriate depends on the clinical question, patient factors, urgency, and local resource availability. Common situations where MRI is often considered include:

• Neurology and neuroemergency pathways
  Brain and spine imaging for suspected ischemia patterns, demyelination, infection, tumors, seizures, or spinal cord pathology, when MRI is feasible within required timeframes.

• Musculoskeletal (MSK) imaging
  Soft tissue injuries (ligaments, tendons), marrow abnormalities, and joint cartilage evaluation, especially when radiographs are nondiagnostic.

• Oncology
  Local staging and characterization of many tumors, and follow-up in selected cancers. MRI may also support radiation planning in some settings.

• Abdominal and pelvic imaging
  Liver lesion characterization, biliary imaging (MRCP in some protocols), pelvic organ evaluation, and problem-solving when ultrasound/CT are limited.

• Cardiac and vascular applications
  Cardiac MRI and MR angiography are specialized services requiring trained teams and specific protocols; suitability is highly facility-dependent.

• Pediatrics
  MRI is often attractive due to lack of ionizing radiation, but motion management and sedation/anesthesia considerations can be limiting factors and require strict institutional pathways.

When MRI may not be suitable (general)

An MRI scanner may be less suitable when:

• Time-critical instability: The patient cannot safely tolerate transport and time in the MRI environment, or continuous support equipment is not MRI-compatible.
• Incompatible implants or foreign bodies: Certain devices or fragments may be unsafe or require detailed device-specific conditions.
• Severe motion risk: The patient cannot remain still, and mitigation options (coaching, immobilization, sedation) are unavailable or inappropriate under local protocols.
• Alternative modality is sufficient and faster: CT, ultrasound, or radiography may answer the question adequately with better availability or fewer constraints.
• Operational constraints: MRI downtime, staffing gaps, or lack of appropriate coils/software may limit feasibility.

Safety cautions and contraindications (non-exhaustive, general)

MRI safety is not only about the scan; it is about the environment. Key caution areas include:

• Implants and devices
  MRI compatibility is often categorized as MR Safe, MR Conditional, or MR Unsafe (labeling conventions can vary). “MR Conditional” means scanning may be possible only under specific conditions (field strength, positioning, scan mode limits, etc.). Device-specific documentation is essential.

• Ferromagnetic objects
  Tools, oxygen cylinders, stretchers, wheelchairs, and personal items can become projectiles. This risk exists even when the scan is not running because the main magnet is typically always on.

• Heating and burns
  RF energy can cause heating, particularly when conductive loops form (e.g., cables touching skin, skin-to-skin contact, ECG leads not MRI-appropriate). Prevention is a core operational discipline.

• Acoustic noise
  Gradient switching creates loud noise. Hearing protection is standard.

• Contrast agents
  Some exams use gadolinium-based contrast agents (GBCAs). Risks and screening requirements depend on patient factors and institutional policy. Use is governed by local protocols and clinician judgment.

Emphasize judgment, supervision, and local protocols

For students and trainees: MRI decisions should be made under supervision with attention to the clinical question and local pathways. For administrators: ensure protocols, staffing, and governance exist so MRI is used appropriately and safely, with clear escalation routes when screening or safety questions arise.

What do I need before starting?

Environment and infrastructure prerequisites

An MRI scanner is not “plug-and-play” hospital equipment. Facilities typically need:

• Physical space planning
  Magnet room, control room, equipment room, and patient preparation areas. Many sites implement access control and clearly marked safety zones.

• RF shielding and magnetic field considerations
  A Faraday cage is commonly used to reduce RF interference. The magnetic fringe field affects where ferromagnetic objects can safely be present.

• Power, cooling, and building interfaces
  Stable electrical supply, grounding, HVAC capacity, and—in some systems—water cooling. Requirements vary by manufacturer and model.

• Cryogen management (for many systems)
  Many MRI magnets use cryogens (commonly helium) to maintain superconductivity. Quench pipe design and venting are major safety engineering topics and must follow manufacturer and local building/safety codes.

• Network and cybersecurity readiness
  Integration with PACS/RIS (Radiology Information System)/EMR (Electronic Medical Record) typically requires secure networking, DICOM configuration, user authentication, and patching policies aligned with the hospital’s cybersecurity program.

Accessories and “MRI-compatible” ecosystem

Beyond the scanner, a working service needs:

• RF coils (head, spine, body, extremity coils; inventory depends on service lines)
• Patient positioning aids (pads, straps, immobilization supports)
• Hearing protection (earplugs/headphones as approved for the environment)
• Two-way communication (intercom, call button)
• MRI-conditional monitoring (pulse oximetry, ECG, blood pressure) when needed
• MRI-safe or MRI-conditional transport equipment (stretchers, wheelchairs)
• Ferromagnetic detection where used (policies and equipment vary)
• Emergency equipment appropriate to MRI zones (availability and labeling per facility policy)

A recurring operational issue is “mixed inventory,” where non-MRI-safe devices accidentally enter restricted areas. Labeling, training, and controlled storage are essential.

Training and competency expectations

Safe MRI operation depends on role-based training, typically including:

• MRI technologists/radiographers trained on scanner operation, protocols, and safety screening.
• Radiologists (and sometimes specialty clinicians) for protocoling and interpretation.
• Nursing staff for IV access, patient assessment, and monitoring workflows (scope varies by country).
• Anesthesia/critical care teams for patients requiring sedation or advanced monitoring, using MRI-compatible equipment.
• MRI Safety Officer and MRI Medical Director roles are used in many organizations to provide governance; job titles and responsibilities vary by institution.

Competency should be documented and refreshed. “One-time orientation” is rarely sufficient for a high-risk environment.

Pre-use checks and documentation

Common pre-use and daily checks include:

• Room readiness: Clear zones, signage visible, door access controls functioning.
• Emergency readiness: Confirm emergency procedures, communication, and zone-appropriate response equipment.
• System QA/QC: Many sites run a daily image-quality check (often with a phantom) to detect drift in signal-to-noise, uniformity, and artifacts (specifics vary by manufacturer and accreditation requirements).
• Coil and accessory inspection: Look for damaged cables, cracked coil housings, or worn insulation that could contribute to burns or signal artifacts.
• Documentation: Patient screening forms, implant documentation, contrast documentation when applicable, and exam logs.

Commissioning, maintenance readiness, and policies

Before clinical go-live, hospitals typically need:

• Acceptance testing and baseline performance: Establish image quality benchmarks and safety checks.
• Service plan and parts strategy: Decide between OEM service, third-party service, or hybrid; ensure response times and coverage meet clinical needs.
• Preventive maintenance schedule: Align with manufacturer recommendations and local regulations.
• Downtime and contingency workflows: Clear plans for urgent imaging when MRI is unavailable.
• Policies: MRI safety policy, screening policy, cleaning policy, incident reporting, and controlled access to restricted zones.

Roles and responsibilities (clinical vs. biomed vs. procurement)

Clear ownership reduces risk:

• Clinicians (ordering teams): Define the clinical question, provide relevant history, and ensure contraindication/implant information is communicated as required by local policy.
• Radiology (radiologist + technologist team): Protocol selection, scan execution, contrast decisions within scope, image quality, and reporting workflow.
• Biomedical engineering/clinical engineering: Asset management, preventive maintenance coordination, safety inspections, and interface with vendors for technical issues.
• IT/health informatics: PACS/RIS integration, cybersecurity controls, user management, and network reliability.
• Procurement and hospital leadership: Vendor selection, contracting, service-level agreements (SLAs), warranty terms, training commitments, and lifecycle planning.

How do I use it correctly (basic operation)?

Workflows vary by model, software version, and local policy. The steps below reflect common, broadly applicable practice for MRI scanner operation.

Step-by-step workflow (universal concepts)

1. Confirm the order and clinical question
   Ensure the requested exam matches the indication and that key history is available (prior imaging, surgery, implants, symptoms). Protocol decisions typically require trained radiology staff.

2. Perform MRI safety screening
   Use a standardized screening process. Confirm implants, prior surgeries, possible metal exposure, and any device identification needed for MR Conditional conditions.

3. Prepare the patient
   Remove metallic items and manage clothing per policy. Explain noise, need to remain still, expected duration, and how to communicate during the scan. Provide hearing protection and a call device.

4. Establish IV access if required
   For contrast studies or emergency medications under local protocols, ensure IV access is placed outside the magnet room if that is facility practice.

5. Position the patient and place the appropriate coil
   Correct positioning improves image quality and reduces repeat sequences. Ensure the coil is intact, correctly connected, and comfortably placed.

6. Set up monitoring and gating if needed
   For sedated patients or physiologic imaging (e.g., cardiac), attach MRI-conditional monitoring equipment. Route cables safely to avoid loops and contact points.

7. Select and tailor the protocol
   Choose an exam protocol appropriate to the clinical question. Adjustments may be needed based on patient size, ability to cooperate, implanted device conditions, and time constraints.

8. Acquire localizers and run sequences
   Scout images confirm anatomy and alignment. Then run ordered sequences in the correct planes. Monitor the patient throughout.

9. Review images for adequacy before removing the patient
   Confirm coverage and basic quality. If motion or artifact compromises diagnostic utility, consider repeating key sequences if the patient can tolerate it and policy allows.

10. Complete post-scan workflow
    Assist the patient off the table, remove monitoring leads, assess immediate tolerance, and provide post-procedure instructions per local practice (especially if sedation or contrast was used). Send images to PACS and complete documentation.

Setup and calibration considerations

MRI scanners perform many calibrations automatically, such as:

• Center frequency adjustments
• Shimming (improving magnetic field homogeneity)
• Coil checks and tuning (model-dependent)
• Prescan normalization (to improve uniformity)

Operators should know which steps are automated versus manual and how to recognize failed calibrations. If repeated prescan failures occur, escalation to biomedical engineering or the service provider is appropriate.

Typical settings and what they generally mean (conceptual)

MRI parameters can be intimidating; the aim here is orientation, not protocol prescription:

• Field strength (e.g., 1.5T, 3T): Higher field strength often improves signal-to-noise but can increase susceptibility artifacts and RF-related constraints; practical performance varies by manufacturer and application.
• TR (repetition time) and TE (echo time): Timing parameters that influence contrast (e.g., T1 vs T2 weighting).
• Slice thickness and gap: Thinner slices improve detail but can increase scan time or reduce signal.
• FOV (field of view) and matrix: Determine spatial resolution and coverage; too small an FOV can cause wrap/aliasing artifacts.
• NEX/NSA (number of excitations/averages): More averaging can reduce noise but increases scan time.
• Bandwidth: Influences noise and artifact trade-offs (implementation differs by vendor).
• SAR or related RF power metrics: Safety-related limits to manage heating; the system enforces limits based on mode and patient inputs, but correct patient data entry matters.

Common “universal” best practices across models

• Enter patient size data accurately (affects safety calculations and image scaling).
• Prioritize motion-sensitive sequences early if motion is expected.
• Use pads and positioning to reduce motion and improve comfort.
• Keep communication active; anxiety and motion are linked.
• Document any deviations from standard protocol and the reason.

How do I keep the patient safe?

MRI safety is a systems discipline. The MRI scanner itself is engineered with interlocks and software limits, but the largest risks often come from process failures: incomplete screening, unauthorized equipment entering the room, or poor cable/coil management.

Core MRI environment risks to control

The magnet is (usually) always on

The static magnetic field is continuously present in many MRI scanners. This means:

• Ferromagnetic objects can accelerate into the bore without warning.
• “Just stepping in for a second” can still be hazardous.
• A strong safety culture is required, not just signage.

Projectile and crush hazards

Common risk items include oxygen cylinders, floor cleaners, tools, some wheelchairs/stretchers, and personal items (phones, keys). Mitigations typically include:

• Zoning and controlled access
• MR Safe/MR Conditional equipment inventory
• Staff training and escorts for non-radiology personnel
• Use of ferromagnetic detection where adopted (policy-dependent)

Implant and device interactions

MRI can affect implants through:

• Movement/torque (mechanical force)
• Heating (RF energy)
• Device malfunction (electronics, reed switches)
• Image artifacts that obscure anatomy

Safe scanning depends on device-specific conditions and documentation, which may include field strength limits, scan mode limits, positioning restrictions, and waiting periods post-implantation (varies by device). When documentation is unclear, escalation pathways (radiology leadership, MRI safety officer, referring team) are essential.

Physiologic safety: heating, burns, and noise

RF heating and burns

Burn risks increase with:

• Conductive loops (cables looped, arms touching torso, legs crossed)
• ECG leads or pulse oximetry cables that are not MRI-conditional
• Metallic fibers in clothing or certain patches
• Poor coil insulation or damaged cable jackets

Common prevention strategies:

• Keep skin-to-skin contact separated with approved padding.
• Route cables straight, avoid loops, and keep them off the skin when possible.
• Inspect coils and leads regularly and remove damaged accessories from service.
• Follow manufacturer guidance for use of blankets, warming devices, and monitoring leads.

Acoustic noise

MRI sequences can be loud. Standard controls include:

• Hearing protection for every patient and anyone in the scan room when sequences run
• Clear communication about expected noise bursts
• Extra caution for pediatric patients and those with sensory sensitivity

Monitoring, communication, and human factors

• Continuous observation: Visual and audio contact reduces anxiety and improves safety.
• Call bell and stop-scan procedures: Patients should know how to signal distress.
• Time-outs and checklists: A brief, consistent pause before entering the magnet room helps prevent errors (wrong patient, wrong implant status, wrong equipment).
• Team role clarity: One person should “own” safety screening completion and zone control during each patient movement.

Contrast safety (general)

Some MRI exams use GBCAs. Safety considerations are governed by institutional policy and may include:

• Screening for kidney function according to local protocol
• Allergy/hypersensitivity history and emergency preparedness
• Documentation of agent, dose, lot number, and any adverse reaction

Policies vary by country, facility, and manufacturer labeling. The key operational principle is consistent screening, clear documentation, and readiness to respond to reactions.

Special populations and scenarios (operational view)

• Sedated/anesthetized patients: Require MRI-compatible monitoring, trained staff, airway and emergency plans tailored to the MRI environment, and clear handoffs.
• Critically ill patients: Need careful planning for transport, line management, oxygen supply, and monitoring in a restricted environment.
• Pediatrics: Motion management and comfort measures are central; caregiver presence policies vary.

Incident reporting and learning culture

MRI safety improves with transparent reporting of:

• Near misses (e.g., metal detected before room entry)
• Process deviations (incomplete screening, door left unsecured)
• Equipment failures and adverse events

A non-punitive reporting culture—paired with meaningful corrective action—reduces repeat events and supports accreditation readiness where applicable.

How do I interpret the output?

MRI output is primarily image data, but it is not “one image.” It is a set of sequences acquired with different contrasts, planes, and sometimes quantitative maps.

Types of outputs you may see

• Standard anatomical sequences
  Examples include T1-weighted and T2-weighted images, with optional fat suppression methods.

• Fluid-sensitive and suppression techniques
  FLAIR (Fluid-Attenuated Inversion Recovery) and STIR (Short Tau Inversion Recovery) are common in neuro and MSK to highlight edema or suppress fat/fluid signals depending on the method.

• Diffusion-weighted imaging (DWI) and ADC maps
  DWI highlights areas of restricted diffusion; ADC (apparent diffusion coefficient) maps help distinguish true restriction from “T2 shine-through.” Interpretation is context-dependent.

• Gradient echo and susceptibility-sensitive imaging
  Useful for blood products, calcification patterns in some settings, and metal-related artifacts (appearance varies by sequence and field strength).

• MR angiography/venography
  Vascular imaging can be performed with or without contrast depending on technique and local practice.

• Post-processing and reconstructions
  Multiplanar reconstructions, 3D renderings, and quantitative outputs may be generated on the scanner console or a separate workstation.

All outputs are typically stored and distributed in DICOM format to PACS, with radiology reports documented in the RIS/EMR.

How clinicians typically interpret MRI (training-oriented overview)

For medical students and residents, MRI reading often starts with a structured approach:

• Confirm patient, date, and exam type.
• Identify sequences and planes.
• Review for gross abnormalities, then focus on the clinical question.
• Compare sides (e.g., symmetric anatomy) when relevant.
• Correlate with history, exam, labs, and prior imaging.

Formal interpretation is performed by trained radiologists (and subspecialists where available). Trainees should use MRI findings to support clinical reasoning, not to replace supervised reporting.

Common pitfalls and limitations

MRI is powerful but not infallible. Common issues include:

• Artifacts
• Motion artifacts (most common in patients who cannot remain still)
• Susceptibility artifacts (near metal, air-tissue interfaces)
• Wrap/aliasing (anatomy appearing in the wrong place due to small FOV)
• Chemical shift and partial volume effects

• Flow-related artifacts in vessels and CSF

• False positives/negatives
  Signal changes can be nonspecific. For example, edema patterns may have multiple etiologies. Conversely, small lesions may be missed if protocols are incomplete, timing is suboptimal, or artifacts obscure anatomy.

• Protocol dependence
  What you can conclude depends on which sequences were obtained and their quality. A “limited” protocol can answer a focused question but may not assess all differential diagnoses.

• Clinical correlation is essential
  MRI findings must be interpreted in clinical context. Radiology reports often include differential considerations; treatment decisions require integrated judgment by the clinical team.

What if something goes wrong?

When problems occur with an MRI scanner, the priority is safety, then preservation of diagnostic quality, then uptime. Troubleshooting should follow local escalation pathways and manufacturer instructions for use (IFU).

A practical troubleshooting checklist

If the issue is patient-related:

• Stop the scan if the patient reports pain, burning, severe anxiety, or cannot continue.
• Check for skin contact points, cable loops, or pressure points.
• Reconfirm hearing protection and communication.
• Consider repositioning, additional padding, or protocol simplification per local practice.

If the issue is image-quality related:

• Identify the artifact type (motion, wrap, susceptibility, RF noise).
• Confirm correct coil selection and secure coil connection.
• Re-run prescan/shimming if the system indicates failure (workflows vary by manufacturer).
• Reduce motion risk (comfort measures, shorter sequences, gating if appropriate and available).
• Check for external RF interference (doors, shielding integrity, nearby equipment), escalating as needed.

If the issue is equipment/alarm related:

• Follow on-screen guidance and local SOPs (standard operating procedures).
• Remove the patient from the bore if safety is uncertain.
• Document the error codes/messages and what was occurring when it happened.
• Notify biomedical engineering and/or the service provider.

When to stop use immediately (general)

Stop the scan and escalate if:

• There is suspected burn, electric smell, smoke, sparks, or abnormal sounds beyond normal gradient noise.
• A ferromagnetic object enters the scan room or is suspected near the magnet.
• The patient’s condition deteriorates and appropriate monitoring/support cannot be maintained in the MRI environment.
• The scanner indicates a critical fault that compromises safety or image integrity.

Emergency response in MRI requires MRI-specific procedures (for example, resuscitation equipment must be appropriate to the zone). Facilities should train staff on code response in and around the MRI suite.

Escalation, documentation, and reporting expectations

• Biomedical/clinical engineering: Evaluate accessory failures (coils, cables), coordinate vendor service, and manage equipment downtime.
• Vendor/manufacturer service: Required for many magnet, gradient, RF amplifier, or cryogen-related issues, and for software faults.
• Safety/quality office: Incident reporting for adverse events and near misses supports learning and compliance.
• Radiology leadership: Decide whether exams can continue under limitations or if service suspension is required.

Document what happened, who was notified, what actions were taken, and whether any patient follow-up was required under local policy.

Infection control and cleaning of MRI scanner

MRI environments have unique infection prevention challenges: high patient throughput, frequent contact surfaces, and accessories that are difficult to clean if not designed for repeated disinfection.

Cleaning principles for MRI areas

• Clean between patients for high-touch surfaces using facility-approved disinfectants compatible with MRI materials.
• Avoid introducing unauthorized equipment (including cleaning tools) into restricted zones; use MRI-safe carts and tools.
• Follow contact time for disinfectants (wet time), as required by the product label and facility policy.
• Separate clean and dirty workflow for coils, pads, and linens to avoid cross-contamination.

Disinfection vs. sterilization (general)

• Cleaning removes visible soil and reduces bioburden.
• Disinfection inactivates many pathogens on surfaces; levels (low/intermediate/high) depend on agent and policy.
• Sterilization is used for critical devices that enter sterile tissue; the MRI scanner itself is not sterilized, but accessories used in invasive procedures may have separate sterile processing pathways (highly facility-specific).

High-touch points on an MRI scanner and accessories

Common high-touch or high-contamination-risk areas include:

• Patient table and side rails
• Coil surfaces and coil padding
• Positioning pads, straps, and sponges
• Call button and cable
• Headphones/ear protection (per IFU)
• Bore opening (front ring) and patient-facing panels
• Control room keyboards/mice (shared equipment)

Example cleaning workflow (non-brand-specific)

1. Don appropriate PPE (personal protective equipment) per facility infection prevention policy.
2. Remove and bag used linens; handle as contaminated.
3. Visually inspect coils and pads for damage; remove damaged items from service.
4. Clean visible soil first, then disinfect patient-contact surfaces (table, coils, pads, call bell).
5. Respect disinfectant wet time; do not shortcut drying times.
6. Allow surfaces to fully dry before the next patient, especially for coil connectors and electronics-adjacent areas.
7. Clean shared control surfaces (keyboard, mouse, console surfaces) at scheduled intervals and when visibly soiled.
8. Document cleaning completion if required by policy (common in high-acuity settings).

Always follow the manufacturer IFU for the MRI scanner and each accessory. Some disinfectants can degrade plastics, adhesives, coil housings, and foam over time, and some cleaning methods can damage electronics.

Medical Device Companies & OEMs

Manufacturer vs. OEM: what the terms mean

• Manufacturer: The company that designs, assembles, and markets the MRI scanner under its brand, and typically holds regulatory responsibility for the finished medical equipment in the jurisdictions where it is sold.
• OEM (Original Equipment Manufacturer): A company that produces components or subsystems used within the final product. In MRI, OEM relationships can involve gradient components, RF electronics, patient monitoring accessories, coils, chillers, or software modules (details vary by manufacturer and are not always publicly stated).

Why OEM relationships matter for hospitals

OEM and supplier networks influence:

• Serviceability and parts availability: Some parts may be proprietary; others may have multiple sources.
• Upgrade paths: Hardware and software upgrades can be constrained by subsystem compatibility.
• Lifecycle cost: Warranty terms, service contracts, and end-of-support timelines affect total cost of ownership.
• Quality systems: Hospitals should ask about quality management, traceability, and service documentation rather than assuming all suppliers operate identically.

Key Takeaways and Practical Checklist for MRI scanner

• Treat the MRI scanner room as a controlled safety environment, not just an imaging room.
• Assume the main magnetic field is always present unless facility leadership confirms otherwise.
• Use standardized screening every time, even for returning patients and staff.
• Never bring unvetted oxygen cylinders, stretchers, or tools into restricted MRI zones.
• Enforce MR Safe / MR Conditional / MR Unsafe labeling and storage discipline.
• Verify implant and device conditions with documentation; do not rely on memory or verbal history alone.
• Create a clear escalation pathway for uncertain implant status or incomplete records.
• Separate skin-to-skin contact points with approved padding to reduce burn risk.
• Route cables straight and avoid loops, especially for monitoring leads.
• Remove damaged coils, frayed cables, and cracked housings from service immediately.
• Provide hearing protection to every patient and anyone present during scanning.
• Explain noise, duration, and communication methods before moving the patient into the bore.
• Confirm the patient has a call device and knows how to stop the exam.
• Prioritize patient comfort to reduce motion and repeat sequences.
• Enter patient size and positioning data accurately to support safety limits.
• Use localizers to confirm coverage before committing to long sequences.
• Review images for adequacy before the patient leaves the scanner area.
• Document protocol deviations and the operational reason (motion, device conditions, time limits).
• Standardize daily QA/QC checks and trend results to spot early performance drift.
• Align preventive maintenance with manufacturer guidance and local regulatory expectations.
• Plan for downtime with clear referral pathways and backup imaging options.
• Keep MRI-compatible emergency response equipment available per zone and policy.
• Train code teams on MRI-specific response procedures and access restrictions.
• Integrate MRI scheduling with inpatient transport and nursing workflows to reduce delays.
• Use checklists and a “time-out” mindset to reduce human-factor errors.
• Design the suite with controlled access, clear signage, and practical patient flow.
• Include biomedical engineering and IT early in site planning and commissioning.
• Confirm PACS/RIS connectivity, DICOM settings, and cybersecurity controls before go-live.
• Maintain an inventory list of coils and accessories with tracking and cleaning status.
• Use manufacturer-approved disinfectants and follow wet-time requirements for cleaning.
• Clean high-touch surfaces between patients, including coils and call buttons.
• Separate clean and dirty linens and pads to reduce cross-contamination.
• Track and investigate near misses to strengthen MRI safety culture.
• Ensure staff competency records are current for technologists, nurses, and support staff.
• Clarify who owns protocoling decisions and after-hours coverage responsibilities.
• Evaluate service contracts by response time, parts availability, and planned uptime targets.
• Consider total cost of ownership, including power, cooling, cryogens, and staffing.
• For refurbished systems, confirm local service capability and parts logistics before purchase.
• Protect the MRI scanner network endpoints with hospital cybersecurity governance.
• Build patient-centered workflows for claustrophobia management and communication.
• Establish clear contrast documentation and adverse reaction procedures per policy.
