What Does an MRI Technologist Do? A Guide for Hiring Managers

If you are writing a job description, evaluating candidates, or trying to understand what an MRI technologist actually does every day, this guide is for you. The MRI tech role is more complex than most people outside of radiology realize, and understanding that complexity will help you hire better, set realistic expectations, and build job postings that attract qualified candidates.

MRI technologists are not “people who push buttons and take pictures.” They are healthcare professionals who operate equipment that costs $1 million to $3 million, make real-time technical decisions that directly affect diagnostic quality, and serve as the primary safety gatekeepers for one of the most powerful diagnostic tools in modern medicine.

The MRI Technologist Role Explained

An MRI technologist (also called an MRI tech or MR technologist) operates magnetic resonance imaging scanners to produce diagnostic images of patients’ internal anatomy. Unlike X-ray or CT, MRI uses strong magnetic fields and radiofrequency pulses rather than ionizing radiation. This makes the technology safer for patients in terms of radiation exposure but introduces a completely different set of safety concerns and technical challenges.

The role requires a combination of technical knowledge, patient care skills, critical thinking, and safety awareness that is difficult to replicate with on-the-job training alone. That is why formal MRI education programs exist and why national certification matters.

Daily Responsibilities Breakdown

Here is what a typical day looks like for an MRI technologist working a standard shift:

Patient Safety Screening

Before any patient enters the MRI suite, the technologist conducts a thorough safety screening. This includes reviewing the patient’s screening questionnaire for implants, metallic foreign bodies, and other contraindications. The tech verifies implant compatibility using manufacturer documentation and MRI safety databases. This process is not a formality. Missed screening items have caused serious injuries and deaths. For a deeper look at MRI safety requirements, see our MRI safety training guide.

Patient Preparation and Positioning

The technologist explains the procedure to the patient, addresses anxiety or claustrophobia, changes the patient into appropriate clothing, starts IV access if contrast will be needed, and positions the patient on the scanner table. Proper positioning and coil placement directly affect image quality. A poorly positioned coil can mean the difference between a diagnostic exam and one that needs to be repeated.

Protocol Selection and Modification

MRI exams are not one-size-fits-all. The technologist selects the appropriate imaging protocol based on the clinical indication, the ordering physician’s request, and the patient’s specific situation. Experienced techs frequently modify protocols in real time. If initial images reveal unexpected findings, the tech may add sequences. If a patient cannot hold still, the tech adjusts for motion. If the clinical question changes mid-exam, the tech adapts.

This requires working knowledge of:

• Pulse sequences (T1-weighted, T2-weighted, FLAIR, diffusion, gradient echo, and many more)
• Imaging parameters (TR, TE, flip angle, slice thickness, field of view, matrix size)
• Anatomy and pathology sufficient to recognize whether images are answering the clinical question
• Scanner-specific software for the particular manufacturer and model in use

Image Optimization

During the scan, the technologist monitors image quality on the console. They assess whether images are free from artifacts, properly positioned, and diagnostically useful. Common issues include:

• Motion artifacts from patient movement
• Susceptibility artifacts from metallic implants
• Flow artifacts in vascular regions
• Aliasing from incorrect field of view settings
• Fat-water swap in certain sequences

An experienced MRI tech catches and corrects these issues during the exam rather than discovering them after the patient has left.

Contrast Agent Administration

Many MRI exams require intravenous gadolinium-based contrast agents. The technologist (where permitted by state scope of practice) starts IV access, reviews the patient’s renal function and allergy history, administers the contrast agent, and monitors for adverse reactions. Contrast administration requires knowledge of dosing, injection rates, timing relative to scan sequences, and recognition of contrast reactions ranging from mild to life-threatening.

Documentation and Communication

After each exam, the technologist documents the procedure, notes any complications or relevant observations, and communicates urgent or unexpected findings to the radiologist. In many facilities, the tech also handles scheduling coordination, equipment quality checks, and supply management.

Technical Skills Required

When evaluating MRI tech candidates, these are the core technical competencies to assess:

Scanner Operation

The candidate should be proficient in operating MRI scanners, ideally including the specific manufacturer (Siemens, GE, Philips, Canon) and model at your facility. Cross-training on multiple platforms is valuable but not always available. Scanner operation includes startup and shutdown procedures, daily quality assurance checks, exam programming, and basic troubleshooting.

Coil Selection and Placement

MRI uses specialized receiver coils for different body parts: head coils, spine coils, knee coils, shoulder coils, cardiac coils, breast coils, and flexible surface coils. The technologist must know which coil to use for each exam and how to position it correctly. Improper coil selection or placement degrades image quality.

Pulse Sequence Knowledge

A competent MRI tech understands the physics behind pulse sequences well enough to modify parameters when needed. They should be able to explain why they would change TE or TR for a given situation, when to use fat saturation versus STIR, and how to optimize sequences for specific clinical questions.

Cross-Sectional Anatomy

MRI technologists must have strong knowledge of cross-sectional anatomy to ensure proper scan coverage and to recognize when images are capturing the area of clinical interest. They also need enough pathology awareness to flag potential urgent findings.

Contrast Agent Protocols

Knowledge of gadolinium-based contrast agents, including types, dosing, contraindications (particularly in patients with reduced renal function), timing protocols, and adverse reaction management.

Soft Skills That Matter

Technical skills get candidates in the door. Soft skills determine whether they succeed.

Patient Communication

MRI exams can take 30 to 90 minutes. The patient lies in a narrow bore, often unable to see the technologist, and must remain as still as possible while the scanner produces loud banging noises. The technologist’s ability to explain the procedure clearly, provide reassurance, and maintain communication throughout the exam directly affects patient compliance and image quality.

Claustrophobia and Anxiety Management

An estimated 5% to 10% of patients experience significant claustrophobia during MRI exams. Experienced techs develop techniques for managing patient anxiety, including clear explanations, breathing exercises, positioning adjustments, and knowing when to suggest sedation. The ability to complete exams with anxious patients without resorting to cancellation saves the facility revenue and the patient a delay in diagnosis.

Pediatric Patient Skills

Scanning children requires patience, creativity, and the ability to work with parents. Pediatric MRI often involves sedation or general anesthesia, adding complexity to the technologist’s responsibilities. Not every tech excels at pediatric work, and if your facility handles significant pediatric volume, this is an important hiring consideration.

Trauma and Emergency Situations

In hospital settings, MRI techs may scan trauma patients, stroke patients under acute time pressure, or critically ill patients with monitoring equipment. This requires calm under pressure, efficient workflow, and the ability to balance speed with safety.

Team Collaboration

MRI techs work closely with radiologists, referring physicians, nurses, front desk staff, and other technologists. The ability to communicate effectively, accept feedback, and work cooperatively in a shared workspace matters more than many hiring managers realize.

MRI Tech vs CT Tech vs X-Ray Tech: Scope Comparison

For hiring managers who are not from a radiology background, understanding how MRI differs from other imaging modalities helps set appropriate expectations.

The key differences: MRI exams take longer, the technology is more complex, the safety model is completely different (magnetic fields vs radiation), and the technologist makes more independent technical decisions during each exam.

Typical Work Environments

MRI technologists work in several settings, each with different expectations:

Hospitals

The largest employer of MRI techs. Hospital MRI departments typically run multiple scanners across extended hours. Technologists may scan emergency, inpatient, and outpatient cases. Hospital roles often include on-call responsibilities and exposure to higher-acuity patients.

Outpatient Imaging Centers

These facilities focus on scheduled, elective MRI exams. The pace is generally more predictable than hospital work, with standard business hours being more common. Outpatient centers often emphasize patient throughput and customer service.

Mobile MRI Units

Some technologists work on mobile MRI trailers that travel between facilities. This involves adapting to different environments regularly, working more independently, and managing the additional logistics of mobile operations. Mobile MRI work often pays well due to the travel component and independence required.

Research Facilities

Academic medical centers and research institutions employ MRI techs to operate research scanners. This work involves experimental protocols, longer scan sessions, and close collaboration with researchers. It can be intellectually stimulating but is a niche market.

Shift Patterns and Scheduling

Understanding typical MRI scheduling helps you write realistic job postings and set expectations during interviews.

• Day shift: Most common, typically 7:00 AM to 3:30 PM or 8:00 AM to 4:30 PM
• Evening shift: 3:00 PM to 11:00 PM, common in hospitals that extend scanner hours
• Weekend shifts: Many facilities now operate scanners on Saturdays and sometimes Sundays to meet demand
• On-call: Hospital MRI techs frequently have on-call responsibilities for emergency scans (stroke protocols, acute spinal cord compression)
• Compressed schedules: Some facilities offer 3x12-hour or 4x10-hour shifts, which can be attractive to candidates

Be transparent about shift expectations in your job posting. “Flexible hours” means nothing. “Every third weekend, on-call one week per month, primarily day shift” means everything.

What Makes a Great MRI Tech

When you are reviewing candidates, look beyond certifications and years of experience. The best MRI technologists share certain characteristics:

1. Problem-solving orientation: MRI exams rarely go exactly as planned. Great techs adapt rather than defaulting to “I could not complete the exam.”
2. Genuine patient care: This shows up in how they describe patient interactions, not just in whether they mention it.
3. Continuous learning: MRI technology changes. Techs who stay current with new sequences, protocols, and scanner features provide more value.
4. Safety consciousness: It should be instinctive, not something they think about only when asked.
5. Attention to detail: Image quality, patient positioning, documentation. The details matter.
6. Composure under pressure: Emergency add-ons, anxious patients, equipment issues. How does the candidate respond?
7. Communication skills: Can they explain complex things simply? Can they work with radiologists, patients, and colleagues effectively?

Red Flags in MRI Tech Candidates

Watch for these during the interview process:

• Vague answers about safety procedures: Every competent MRI tech should be able to walk you through screening protocols without hesitation
• Inability to describe protocol modifications: If a candidate has never adjusted imaging parameters, their experience may be limited to following pre-programmed exams
• Negative framing of every previous employer: One bad experience is normal. A pattern suggests the candidate is the common factor
• No questions about your equipment: A tech who does not ask what scanner you have, what software version you run, or what protocols you use is not engaged
• Resistance to continuing education: MRI is a field where standing still means falling behind
• Cannot name specific challenging cases: Experienced techs have stories. If they cannot describe a difficult scan and how they handled it, their experience may be thinner than their resume suggests

Building Your Job Description

Based on everything above, here is a practical job description structure. For a ready-to-use template, see our MRI technologist job description template.

Job Title

Use “MRI Technologist” as the primary title. Avoid non-standard titles that candidates will not search for. You can include alternates: “MRI Technologist (MR Tech / MRI Tech).”

Summary

Two to three sentences covering what the role involves, where the person will work, and what makes your facility worth considering. Be specific, not generic.

Responsibilities

List 10 to 15 specific duties, starting with the most important. Use the daily responsibilities section above as your source.

Required Qualifications

Keep this realistic. If you require ARRT(MR) or ARMRIT certification, state it. If you will consider new graduates, say so. If you need experience on a specific scanner, include it. Do not list 15 requirements when 6 are actually essential. For details on certification types, see our ARRT vs ARMRIT comparison guide.

Preferred Qualifications

This is where you list nice-to-haves: cardiac MRI experience, specific scanner platform experience, BLS/ACLS certification, prior hospital experience, etc.

Compensation and Benefits

Include a salary range. The current MRI technologist salary data shows a national median of approximately $63,170. If you are competitive, showing the range helps attract applicants. If you are below market, at least you are being honest and avoiding wasted interviews.

Physical Requirements

MRI work involves lifting patients, standing for extended periods, and working in a confined space. Include this for compliance purposes.

Where to Find MRI Tech Candidates

The MRI staffing shortage means you are competing for a limited pool. Cast a wide net:

• Indeed, LinkedIn, ZipRecruiter: The standard job boards. Post and actively search for candidates.
• ASRT Job Board: Targeted to radiologic technologists.
• RadWorking, RT Jobs: Specialty boards for radiology professionals.
• State radiologic technology societies: Many maintain job boards and email lists.
• Training programs: Build relationships with local MRI training programs. Graduates need jobs; you need techs. See our guide on becoming a clinical training site.
• Professional conferences: RSNA, SMRT, and state society meetings are networking opportunities.
• Employee referrals: Your best techs know other good techs. Referral bonuses work.

The Case for Growing Your Own: Training Existing Staff

If you cannot find experienced MRI technologists, and increasingly many facilities cannot, consider training your own. This approach works particularly well for:

• Healthcare workers already at your facility (patient care techs, X-ray techs, nurses) who want to advance
• New hires without MRI experience but with the right aptitude and work ethic
• Facilities in rural or underserved markets where recruitment is especially difficult

Programs like Tesla MR Institute offer ARMRIT-accredited MRI training that takes 12 to 18 months and does not require prior radiology certification. Clinical rotations can often be arranged at the sponsoring facility, so you are building your pipeline directly.

The economics are straightforward. Training an MRI tech in-house costs a fraction of what you will spend on travel technologists or unfilled positions over the same period. Our employer training guide breaks down the costs and logistics.
