ARRT’s Magnetic Resonance Imaging examination is a 200-scored-question, computer-based examination — plus unscored pilot questions — across four content categories (Patient Care, Safety, Image Production, and Procedures), passed at a total scaled score of 75 on ARRT’s 1-to-99 scale. Through the postprimary pathway it is open to technologists who already hold a supporting credential, and who complete 16 hours of structured education and ARRT’s documented MRI clinical experience requirements within the 24 months before applying. PassProfessor’s companion practice program is in the works, built to the content specifications.

Most examination guides start with the test. For the postprimary MRI candidate, that is the wrong starting point: the examination is the last of three requirements, and the first two run on a clock that does not wait for you to finish studying. This guide therefore does two jobs in the open. It walks the postprimary pathway itself — supporting credential, structured education, clinical experience, ethics, application — with the timing rules that govern each piece. And it walks ARRT’s content specifications category by category with a preparation method for each, explains the scaled scoring rule, and ends with a study plan that runs the pathway and the preparation in parallel, which is the only way the postprimary route actually fits a working technologist’s calendar. Everything factual comes from ARRT’s published materials recorded in this guide’s internal sources section.
Which examination is this?
This guide covers certification and registration in Magnetic Resonance Imaging from the American Registry of Radiologic Technologists (ARRT), earned through the postprimary eligibility pathway — the route for technologists who already hold a credential and are adding MRI. ARRT also offers MRI through a primary pathway, built on completing an educational program in the discipline; both pathways end at the same examination and the same credential, and MRI is one of the few ARRT disciplines available both ways. This guide does not cover the separate MRI credential of ARMRIT, a different registry. State licensing, where it exists, is a separate matter from ARRT certification and registration.

The postprimary pathway, step by step
Step 1 — Hold the supporting credential. Postprimary eligibility starts from certification and registration you already have. You must be ARRT certified and registered in an appropriate supporting category for MRI. ARRT also recognizes, in some cases, certification by the Nuclear Medicine Technology Certification Board (NMTCB) or the American Registry for Diagnostic Medical Sonography (ARDMS) as the supporting category — the MRI postprimary route is one of the places that cross-recognition applies. If you hold none of these, the postprimary door is closed and the primary pathway (an MRI educational program) is your route instead.
Step 2 — Complete 16 hours of structured education. Structured education is ARRT’s mechanism for making sure the examination’s content has actually been taught to you, not merely encountered. The requirement: 16 hours of activities targeted to reflect the MRI Examination Content Specifications, including at least one credit from each of the document’s major content categories. Activities must be approved by a CE approver or state entity, or be academic courses from an institution accredited by an ARRT-recognized agency — the same criteria that govern biennial CE. All 16 hours must fall within the 24 months before you submit your postprimary application.
Step 3 — Document the clinical experience. MRI has its own clinical experience requirements document: a defined set of procedures, structured as mandatory procedures you must demonstrate and elective procedures you choose among, with a minimum of 125 repetitions documented in total, across a minimum range of different procedures. You log each procedure through your online ARRT account and a verifier confirms your work. The timing rule is the same 24-month window — and it has teeth: until you apply, logged procedures older than the window expire automatically. Once you apply and are assigned your examination window, the procedures lock in and stop expiring. The practical consequence: document contemporaneously, apply when the documentation is complete, and do not let a finished clinical log sit unapplied while its oldest entries age out.
Step 4 — Ethics and application. You must meet ARRT’s ethics requirements, as for every ARRT credential. You then submit the postprimary application and ARRT’s application fee — the fee depends on the credential route you apply under, so confirm the current amount in ARRT’s postprimary handbook for your route — and, once approved, schedule the examination at a standardized testing center within your assigned examination window.
Step 5 — Pass, then maintain. Passing the examination completes the credential. Like all ARRT credentials, MRI certification and registration is maintained through ARRT’s continuing education requirements on the biennial cycle and its Continuing Qualifications Requirements (CQR) on the ten-year cycle — the structured self-assessment ARRT publishes for MRI is part of that later maintenance, not of initial eligibility.
The content specifications, category by category
ARRT’s Examination Content Specifications for Magnetic Resonance Imaging organize the examination into four major categories. The specifications assign Image Production the largest share of the examination and Procedures the next largest; Patient Care and Safety complete the four. Exact per-category question counts are published in ARRT’s specifications document for the version in force on your examination date — the study guidance below follows the categories and their published structure.
Patient Care — patient interactions and management
The specifications cover how the technologist interacts with and manages the patient across the MRI examination: communication and education, assessment, monitoring, and care during a procedure in which the patient is inside a bore, often for a long examination, sometimes anxious or claustrophobic, sometimes sedated or critically ill. Preparation method: review patient care as an MRI-specific discipline rather than a generic one. The tested judgments are about what changes when the patient is in the magnet environment — what can and cannot accompany them, how monitoring is maintained, how emergencies are recognized and reached. Candidates with strong general patient-care habits score here by adapting those habits explicitly to the magnet, item by item.
Safety — MRI screening and safety
Safety covers the screening process and the magnetic environment: screening patients and personnel, evaluating implants, devices, and foreign bodies, the hazards of the static magnetic field, gradient fields, and radiofrequency energy, projectile risk, contrast agents used in MRI and contrast-related complications, and emergency response. Preparation method: study safety as a set of decision rules, because that is how it is tested. For every device or condition, the question is disposition — scan, scan with conditions, or do not scan — and the reasoning that produces it. Contrast safety follows the same pattern: agent properties, patient factors, complications, and response. This is also the category where experience in another modality can mislead: none of MRI’s principal hazards involve ionizing radiation, and the screening discipline that replaces radiation protection has to be learned on its own terms.
Image Production — principles, parameters, and data
The largest category, in three subcategories. Physical principles of image formation covers the physics underneath the image: the magnetic environment, proton behaviour, signal generation, relaxation, and image formation. Sequence parameters and options covers the pulse sequences available to the technologist and the parameter trade-offs — signal-to-noise, contrast, spatial resolution, acquisition time, and artifact — that every protocol decision balances. Data acquisition, processing, and storage covers sampling and manipulation of the data (the specifications reach concepts such as the Nyquist theorem), reconstruction, post-processing, and storage. Preparation method: refuse to study any principle without its consequence. For each concept, force two questions — what does this look like on the image when it changes, and which parameter would a technologist move to change it? Candidates who can run those two questions in both directions own this category; candidates who memorized definitions own a vocabulary the items will not reward.
Procedures — neurological, body, and musculoskeletal
Procedures covers the examinations themselves, organized by region: neurological, body, and musculoskeletal. For each region the specifications expect regional anatomy and pathology, patient positioning and preparation, and protocol selection — planes, sequences, and contrast use — matched to the clinical question. Preparation method: study by clinical indication. Take the common presentations for each region and build outward: what is being asked clinically, what the standard protocol is, why each sequence is in it, and what finding each sequence exists to reveal. Anatomy review rides along naturally in this frame, and it sticks better than anatomy reviewed as lists.
How scoring works
ARRT’s examinations report scaled scores, and MRI is no exception: your total scaled score runs from 1 to 99, and 75 is the score required to pass. The scaled score is a transformation of your performance designed to mean the same thing from one form of the examination to another; it is not a percentage, not a percentile, and not a count of correct answers, and ARRT publishes no formula for converting one into the other. The examination includes unscored pilot questions alongside the 200 scored questions, unidentified, so time and effort must be spent evenly across everything you are shown. With about 230 questions in roughly 210 minutes, the arithmetic pace is a little under a minute per question — brisk enough that the examination punishes long stalls, and generous enough that a candidate who flags, moves, and returns finishes comfortably.
A study plan that runs the pathway and the preparation together
Track 1 — Pathway (start immediately, run throughout). Confirm your supporting credential qualifies. Begin structured education early, checking that your 16 hours spread across all four content categories. Document clinical procedures as you perform them — never in retrospect — and watch the 24-month window on your earliest entries. Apply when the documentation is complete, not when you feel ready to test: applying locks the procedures in.
Track 2 — Knowledge (start with your structured education). Use the structured-education hours as the skeleton of your study and the specifications as the map. Work Image Production first and longest — it is the largest category and the least transferable from other modalities — running every principle through its image consequence and its parameter lever. Work Safety second, as decision rules. Then Procedures by region and indication. Patient Care last and lightest, adapted explicitly to the magnet environment.
Track 3 — Sittings (final month). Sit full timed practice at the real examination’s shape, review misses by category, and re-drill the category that costs you. Enter the final week with the pathway paperwork already approved, so the only remaining variable is the examination itself.
What makes this test demanding
The postprimary MRI examination tests a discipline its candidates are still entering. Image Production assumes physics fluency that other modalities do not build; Safety assumes a hazard model that contradicts habits formed around ionizing radiation; Procedures assumes regional anatomy and protocol logic at working speed. The candidates who pass comfortably are rarely the ones with the most MRI hours — they are the ones who studied the specifications as four distinct subjects and gave the two least familiar subjects, physics and safety, the most time.
How the four categories connect in a single sitting
Study the categories separately, by all means — the plan above does exactly that. But sit the examination as if they were one subject, because in the room they are. A Procedures item about a neurological examination quietly assumes Image Production reasoning: the protocol named in the stem is there for a reason, and the item is often testing whether you understand what that sequence contributes, not merely whether you recognize its name. A Patient Care item about a patient who becomes distressed inside the bore is also a Safety item in disguise — the correct response has to respect both the patient’s condition and the magnetic environment the response takes place in. A Safety item about an implant disposition changes the Procedures answer that follows it in your own reasoning, even when the items themselves are unrelated, because disposition is the gate through which every protocol decision must pass.
That interdependence suggests a specific study habit: after you have learned a topic inside its own category, deliberately re-ask it from the neighbouring category’s point of view. Take a protocol you have learned for a body region and ask three further questions. What parameter trade-off is this protocol accepting, and what would change if you moved the lever the other way? What screening question has to be settled before this examination can start at all? What does the technologist owe this particular patient — anxious, sedated, in pain, or unable to communicate clearly — while the examination runs? None of those questions requires new material. Each one reuses material you already have, in the combination the examination itself uses. Candidates who practise that recombination in study find that unfamiliar items feel less unfamiliar, because the unfamiliarity is usually in the combination, not in the underlying content.
Worked reasoning helps here more than re-reading does. When you miss a practice item, resist the habit of noting only the correct answer. Write down, in a sentence, the chain that should have produced it: the finding or condition in the stem, the category that finding belongs to, the decision rule or principle it triggers, and the point at which a plausible wrong option breaks that chain. Most wrong options on this examination are not random; they are the answer a neighbouring category would have given, or the correct principle applied to the wrong patient, device, or region. Naming the break point teaches you to spot the same construction next time, in different clothing. Over a preparation cycle, a notebook of break points becomes a more useful final-week document than any set of summaries, because it records your errors in the examination’s own logic rather than in a textbook’s order.
One further habit ties the categories together in daily practice: use your clinical work itself as a study instrument while you are documenting it. Each procedure you log presents, in real form, the same combination the examination presents on paper — a patient to care for, a screening decision to settle, an image to produce well, and a protocol chosen for a clinical reason. Before you leave a case, spend a minute naming those four elements explicitly and asking which of them could have gone differently, and what you would have done then. That minute costs almost nothing inside a working week, it makes the documented experience do double duty, and it builds exactly the cross-category reasoning that a specifications list, read passively, cannot build on its own.
Common preparation mistakes on the postprimary route
The first mistake is calendar-shaped, and it has nothing to do with knowledge: treating the pathway as paperwork to be finished after studying, instead of as a parallel track with its own expiry dates. The structured education hours and the documented clinical procedures both live inside the same window described earlier in this guide, and the procedures age out until the application locks them in. A candidate who studies brilliantly for months while a completed clinical log quietly expires has not lost study time — they have lost eligibility time, which is harder to replace. The correction is administrative, not academic: start the log early, document as you go, and apply when the documentation is complete.
The second mistake is studying Image Production as a vocabulary list. Definitions feel productive — they can be highlighted, memorized, and tested with flashcards — but the category rewards consequence, not vocabulary. If you cannot say what changes on the image when a parameter moves, and which parameter you would move to achieve a stated change, the definition has not yet become usable knowledge. Test yourself in both directions, principle to image and image to principle, and treat any concept you can only run one way as unfinished.
The third mistake is importing another modality’s safety instincts and calling the job done. Experience elsewhere in imaging is a genuine asset for patient care, positioning, and professional judgement, and a genuine liability where the hazard model differs. MRI safety has to be learned as disposition reasoning — for this patient, this device, this condition: proceed, proceed with conditions, or do not proceed, and why. Candidates who reduce that reasoning to a memorized list of permitted and forbidden objects are exposed the moment an item varies the condition, the patient, or the circumstance, which is precisely what well-written items do.
The fourth mistake is studying Procedures as anatomy lists. A list tells you what is in a region; the examination asks what you would do about a clinical question in that region. Anchor each region to its common presentations, build the protocol outward from the question being asked, and let the anatomy arrive attached to the sequences that exist to reveal it. If your notes for a region contain no clinical questions, they are not yet examination notes.
The fifth mistake is pacing discovered too late. A long sitting with unscored pilot items mixed among the scored ones rewards even effort and punishes long stalls, as the scoring section above explains. That is a trainable behaviour, not a temperament: practise flagging an item that is consuming time, moving on without rancour, and returning with fresh attention. Candidates who only ever practise untimed, topic by topic, meet that discipline for the first time on the day it counts.
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.
How long is the ARRT MRI exam? About three hours and 30 minutes for the full sitting, at a standardized testing center.
What score passes the ARRT MRI exam? A total scaled score of 75 or higher on ARRT’s 1-to-99 scale. It is not a percentage.
What are the four content categories? Patient Care; Safety; Image Production — the largest category, covering physical principles of image formation, sequence parameters and options, and data acquisition, processing, and storage; and Procedures, covering neurological, body, and musculoskeletal examinations.
Who is eligible for the postprimary MRI pathway? Technologists holding ARRT certification and registration in a supporting discipline — or, in some cases, an NMTCB or ARDMS credential as the supporting category — who meet the structured education, clinical experience, and ethics requirements.
How much structured education do I need? 16 hours, targeted to the MRI content specifications with at least one credit from each major content category, completed within the 24 months before you apply.
How many clinical procedures must I document? MRI’s clinical experience requirements call for a minimum of 125 repetitions across the required range of mandatory and elective procedures, documented through your ARRT account and confirmed by verifiers, within the 24 months before application. ARRT’s MRI clinical experience requirements document carries the full procedure list.
Do my logged procedures expire? Yes — until you apply. Procedures outside the 24-month window expire automatically while you are still logging; once you apply and your examination window is assigned, your documented procedures lock in.
Is there a primary pathway to ARRT MRI? Yes — through completion of an MRI educational program. Both pathways lead to the same examination and credential. This guide covers the postprimary pathway.
What does the exam cost? ARRT charges an application fee that depends on the credential route you apply under. Confirm the current amount in ARRT’s postprimary handbook for your route when you apply.
Does the PassProfessor program count as structured education? No. Structured education activities must meet ARRT’s criteria — approval by a CE approver or state entity, or an academic course from an appropriately accredited institution. This program is examination preparation only.
Are PassProfessor’s questions the real exam questions? No. They are original practice questions written to ARRT’s published content specifications. ARRT does not release its examination questions.
