ARRT certification and registration in Magnetic Resonance Imaging through the postprimary pathway starts from a credential you already hold: you must be ARRT certified and registered in a supporting discipline — or hold a qualifying NMTCB or ARDMS credential — complete 16 hours of structured education and ARRT’s documented clinical experience requirements, and pass an examination of 200 scored questions across Patient Care, Safety, Image Production, and Procedures, at a total scaled score of 75 or higher on ARRT’s 1-to-99 scale. PassProfessor’s ARRT MRI program is in the works, built to ARRT’s published content specifications.

MRI is the credential radiographers, CT technologists, nuclear medicine technologists, sonographers, and radiation therapists add when they move into the magnet — and the postprimary pathway is built for working technologists, not students. There is no second degree and no new program admission: there is a supporting credential, a defined block of structured education, a documented set of clinical procedures, and one demanding examination. PassProfessor’s ARRT MRI program is in the works as part of the expanding PassProfessor catalog, built on ARRT’s published Examination Content Specifications for Magnetic Resonance Imaging and organized around the specifications’ four content categories — Patient Care, Safety, Image Production, and Procedures.
Which examination is this?
This page covers one credential only: certification and registration in Magnetic Resonance Imaging from the American Registry of Radiologic Technologists (ARRT), earned through the postprimary eligibility pathway. ARRT also offers MRI through a primary pathway — a full educational program route for candidates entering the discipline from the start — and this page is not about that route, though both pathways lead to the same examination and the same credential. MRI is one of the few ARRT disciplines offered both ways. The credential is also distinct from the separate MRI credential offered by ARMRIT, a different registry with its own examination; nothing on this page concerns that examination. Keeping the pathways and registries separate matters, because postprimary eligibility is the whole ballgame here: if the supporting credential, structured education, or clinical documentation is missing, there is no examination appointment to prepare for.
What will the program cover?
Original practice questions, written to the published content specifications. The program is being built from scratch against ARRT’s Examination Content Specifications for Magnetic Resonance Imaging — Patient Care, Safety, Image Production, and Procedures — so practice follows the examination’s real structure rather than a textbook’s. No practice item is an actual examination item, a recalled item, or another provider’s material, and no item asks you to recite a code, section number, or citation: knowledge and imaging judgment are tested, citations never are.
Physics taught as decisions, not just definitions. Image Production is the specifications’ largest territory — physical principles of image formation, sequence parameters and options, and data acquisition, processing, and storage. The program’s design treats every principle as the answer to a practical question: what changes, what artifact appears, what the image gains or loses when a parameter moves. That is the form in which the examination asks physics, and the form in which a working technologist uses it.
Results you can read by category. Practice is organized by the specifications’ four content categories, so your results can be read category by category: a thin category shows while there is still time to repair it, instead of hiding inside an overall score.
Timed practice at the real sitting’s shape. The real examination presents 200 scored questions plus additional unscored pilot questions in a single sitting of about three and a half hours. The program’s design includes sustained timed practice modelled on that shape, so pacing is trained alongside knowledge.
What are the verified facts of the real exam?
| Fact of record | Detail |
|---|---|
| Credential | Certification and registration in Magnetic Resonance Imaging — R.T.(MR)(ARRT) — from the American Registry of Radiologic Technologists (ARRT) |
| Pathway covered here | Postprimary eligibility pathway. ARRT also offers a primary pathway to the same credential and examination |
| Supporting credential | You must hold ARRT certification and registration in an appropriate supporting discipline; in some cases a Nuclear Medicine Technology Certification Board (NMTCB) credential or an American Registry for Diagnostic Medical Sonography (ARDMS) credential serves as the supporting category |
| Structured education | 16 hours of structured education, targeted to the MRI Examination Content Specifications with at least one credit from each major content category, completed within the 24 months before you submit your postprimary application |
| Clinical experience | Documented clinical experience requirements specific to MRI — procedures performed and documented through your ARRT account and confirmed by verifiers, including a minimum of 125 repetitions across the required range of procedures, completed within the 24 months before application |
| Ethics | You must meet ARRT’s ethics requirements, as with every ARRT credential |
| Format | 200 scored multiple-choice questions, plus additional unscored pilot questions, in one computer-based sitting of about 3 hours 30 minutes at a standardized testing center |
| Content categories | Patient Care; Safety; Image Production (physical principles of image formation; sequence parameters and options; data acquisition, processing, and storage); Procedures (neurological, body, and musculoskeletal examinations) |
| Scoring | Total scaled scores run from 1 to 99; a total scaled score of 75 is required to pass. A scaled score is not a percentage |
| Application fee | ARRT charges an application fee for the postprimary examination; the amount depends on the credential route you apply under — confirm the current fee in ARRT’s postprimary handbook when you apply (see the internal sources note in the companion guide) |
How does the practice map to the content specifications?
ARRT organizes the examination into four major content categories. The practice program is organized on the same categories, and the specifications give Image Production the largest share of the examination, with Procedures next:
| Content category | What it carries |
|---|---|
| Patient Care | Patient interactions and management: communication, assessment, monitoring, and care of the patient through the examination |
| Safety | MRI screening and safety: the screening process, the magnet environment, implants and devices, contrast agents and their complications, and emergency response |
| Image Production | Physical principles of image formation; sequence parameters and options; data acquisition, processing, and storage — the physics and technique core of the examination |
| Procedures | Neurological, body, and musculoskeletal examinations: anatomy, pathology, positioning, and protocol selection by region |
What does Patient Care cover?
The patient side of the magnet: interactions and management from screening interview through the end of the examination — communication, patient assessment and monitoring, care of patients who are anxious, claustrophobic, sedated, or critically ill, and the technologist’s responsibilities while a patient is in the bore. It is the smallest of the four categories, and the one most directly continuous with the practice you already have from your supporting discipline.
Patient Care items are usually won on sequence and vigilance: what you check, ask, and monitor — and in what order — around a patient who cannot be watched the way an x-ray patient is watched.
What does Safety cover?
The category that makes MRI unlike every other imaging examination: MRI screening and safety. Screening of patients, personnel, and anyone entering the magnet environment; the static field, gradient, and radiofrequency hazards; implants, devices, and foreign bodies and how each is evaluated; projectile risk; acoustic noise; contrast agents used in MRI and contrast-related complications; and emergency procedures, from quench events to a patient in distress inside the bore. Safety knowledge in MRI is not general radiation-safety knowledge transferred over — the hazards are different in kind, and the examination tests them in kind.
Never import an x-ray intuition into the magnet. If an option treats the MRI suite like a radiation area, it is answering a question from a different discipline.
What does Image Production cover?
The largest category, in three parts. Physical principles of image formation: the physics of the magnetic environment, signal generation, relaxation, and the formation of the image itself. Sequence parameters and options: the pulse sequences a technologist selects and adjusts, and the trade-offs each parameter carries — signal, contrast, resolution, time, and artifact. Data acquisition, processing, and storage: how data are sampled and manipulated (the specifications reach concepts such as the Nyquist theorem), reconstructed, processed, and stored. This category is where postprimary candidates from non-MRI disciplines feel the distance most: it assumes fluency, not familiarity.
Every parameter question is a trade-off question. The correct option is the one that names what is gained and accepts what is lost; options that promise improvement at no cost are the distractors.
What does Procedures cover?
The applied anatomy-and-protocol category, in three regions: neurological examinations, body examinations, and musculoskeletal examinations. For each region the specifications expect the anatomy and pathology a technologist must recognize, the positioning and patient preparation each examination requires, and the protocol choices — planes, sequences, contrast use — that each clinical question calls for. Procedures is where physics meets the schedule: a candidate can understand sequence parameters in the abstract and still miss the item that asks which protocol answers a specific clinical question about a specific joint, organ, or lesion.
Study procedures by clinical question, not by anatomy list: what is being ruled out decides the protocol, and the protocol decides the parameters.
How is the ARRT MRI examination scored?
ARRT reports a total scaled score between 1 and 99, and a total scaled score of 75 is required to pass. A scaled score is a conversion of performance built to hold the same meaning across examination forms — it is not a percentage of questions answered correctly, and ARRT does not publish a conversion from raw count to scaled score. The examination’s 200 scored questions are supplemented by unscored pilot questions that are not identified, so every question must be answered as if it counted. The practical reading for preparation: Image Production and Procedures together carry the clear majority of the specifications’ weight, so preparation is won there first — but Safety is the category where a working technologist’s existing habits, imported from another modality, are most likely to be actively wrong, and it is large enough to decide a borderline result.
Who can take this exam, and what does it certify?
The postprimary pathway has three requirements, in ARRT’s own frame: education, ethics, and examination. Education means holding the supporting credential, completing the 16 hours of structured education within the 24 months before you apply — with at least one credit earned in each of the specifications’ major content categories — and completing MRI’s clinical experience requirements in the same window, documenting procedures through your ARRT account for verification. One timing rule deserves emphasis: until you apply, logged procedures that fall outside the 24-month window expire; once you apply and your examination window is assigned, your documented procedures lock in. Passing the examination completes the pathway and earns certification and registration in Magnetic Resonance Imaging — the right to use R.T.(MR)(ARRT) — maintained thereafter under ARRT’s continuing education and ethics requirements, like every ARRT credential. A primary pathway to the same credential exists for candidates completing an MRI educational program; it is a different front door to the same examination room.
What makes this test demanding?
Two features. First, the physics depth: Image Production assumes a working command of principles that technologists from x-ray-based disciplines may never have had to use, and it tests them as trade-offs rather than definitions. Second, the breadth across four unlike categories in one sitting: a candidate moves from implant safety to sequence parameters to neuroanatomy to patient monitoring within a handful of questions, and the preparation that works is correspondingly four preparations, not one. Candidates who treat the MRI examination as “my current job, plus a test” underprepare the two categories — physics and MRI-specific safety — where their current job has not already taught them the tested content.
An honest note on format
Every PassProfessor practice question is a single-answer, four-option item, matching the real examination’s multiple-choice format in shape. ARRT does not release its examination questions, and no provider can offer them. Practice here builds the knowledge and judgment the content specifications require; it does not reproduce the examination itself, and it cannot document your clinical procedures or deliver structured education — those parts of the pathway are yours to complete through ARRT-approved routes. Practice results are a study gauge — a way to see which categories are thin while there is time to repair them — not a prediction of a scaled score.
How should you use this page while the program is in the works?
- Join the notify list today. Enrollment is not open yet, and the notify list is how you hear the moment it is. While you wait, read the exam guide — it walks the postprimary requirements step by step and the content categories in full.
- Work the pathway in parallel with the studying. Structured education and clinical documentation run on a 24-month clock; starting them late delays your application no matter how ready your knowledge is. Confirm your supporting credential qualifies, and log procedures from your first MRI rotation.
- Study from the official specifications now. The published content specifications summarized on this page are the syllabus; organizing your reading by their categories is useful work today, before any practice program opens.
- When the program opens, survey every category first. Early practice should touch all four categories, so your first category-by-category picture of yourself is honest — then drill the category that costs you, which for most postprimary candidates is Image Production.
Frequently asked questions
How many questions are on the ARRT MRI exam? 200 scored multiple-choice questions, plus additional unscored pilot questions that are not identified. The sitting runs about three hours and 30 minutes.
What score passes the ARRT MRI exam? A total scaled score of 75 or higher on ARRT’s 1-to-99 scale, as ARRT publishes it. A scaled score is not a percentage of questions answered correctly.
Who can take the MRI exam through the postprimary pathway? Technologists already certified and registered with ARRT in a supporting discipline — and, in some cases, holders of NMTCB or ARDMS credentials, which ARRT accepts as the supporting category for MRI — who also complete the structured education and clinical experience requirements and meet ARRT’s ethics requirements.
What is the structured education requirement? 16 hours of structured education targeted to the MRI content specifications, including at least one credit from each major content category, completed within the 24 months before you submit your postprimary application.
What clinical experience must I document? MRI’s clinical experience requirements: a defined set of procedures performed and documented through your ARRT account and confirmed by verifiers, including a minimum of 125 repetitions across the required range of procedures, within the 24 months before application. ARRT’s MRI clinical experience requirements document lists the procedures and their mandatory and elective structure.
Is there a primary pathway to the same credential? Yes. Candidates who complete an MRI educational program can earn the same credential through ARRT’s primary pathway, and both pathways lead to the same examination. This program is built for the postprimary candidate.
Is the ARRT MRI credential the same as ARMRIT certification? No. ARMRIT is a separate registry with its own examination. This program prepares you for ARRT’s examination only.
What does the ARRT MRI exam cost? ARRT charges an application fee that depends on the credential route you apply under. This page does not print a figure because ARRT’s fee differs by route; confirm the current amount in ARRT’s postprimary handbook when you apply.
Does this program give me structured education credit or clinical documentation? No. It is examination preparation. Structured education must come through activities that meet ARRT’s criteria, and clinical procedures must be documented and verified through ARRT.
Are these the real exam questions? No. Every question in the program is an original PassProfessor practice question written to ARRT’s published content specifications. ARRT does not release its examination questions, and no provider can offer them.
When will enrollment open? The program is in the works. Join the notify list on this page and we will email you when enrollment opens.
