A good MRI registry review starts with the blueprint of the exam you are actually sitting. There are two MRI registries in the United States, ARRT (MR) and ARMRIT, and both are physics-heavy: on the ARRT exam, 106 of 200 scored questions are image production. This page puts the two blueprints side by side, tells you what to study first, gives you a 12-week plan, and points you to free practice questions.
The two MRI registry exams at a glance

The ARRT figures come from ARRT’s MRI examination content specifications, in effect since February 2025. Check the current version on arrt.org before you build your plan, and ARMRIT’s current terms on armrit.org.
What the ARRT MRI exam covers, by question count
| Content area | Scored questions | Share |
|---|---|---|
| Patient care | 16 | 8% |
| Safety | 21 | 10.5% |
| Image production (physical principles, sequence parameters and options, data acquisition and processing) | 106 | 53% |
| Procedures: neurological | 25 | 12.5% |
| Procedures: body | 15 | 7.5% |
| Procedures: musculoskeletal | 17 | 8.5% |
Key Takeaway
More than half the ARRT exam is image production. If your review time is split evenly across topics, you are under-studying the section that decides whether you pass.
The ARMRIT exam covers the same ground in three sections: MRI physics and instrumentation, clinical applications by body region, and MRI safety with cross-sectional anatomy. ARMRIT tests cross-sectional anatomy directly, so expect to identify structures on axial, sagittal, and coronal images.
What to study first
- Physics and image production. Relaxation and contrast (T1, T2, proton density), TR, TE, TI and flip angle, spin echo against gradient echo, inversion recovery, k-space, the trade-offs among signal-to-noise, resolution, and scan time, parallel imaging, and fat suppression methods.
- Artifacts. For each one, know what it looks like, what causes it, and the fix: motion, aliasing, chemical shift, susceptibility, truncation, zipper, and flow.
- Procedures and anatomy. Standard protocols by region, coil choice, positioning, and landmarks, plus identifying structures in all three planes.
- Safety. The four zones, screening, implants and conditional devices, SAR and heating, quench procedures, contrast screening and reactions, and pregnancy.
- Patient care. Communication, consent, monitoring, infection control, and emergencies. It is the smallest section; do not leave it for the morning of the exam either.
A 12-week MRI registry review plan
| Weeks | Focus | What done looks like |
|---|---|---|
| 1 to 4 | Physics and image production | You can explain why changing TR, TE, flip angle, matrix, or bandwidth changes the image, without notes |
| 5 to 8 | Procedures, protocols, and cross-sectional anatomy | You can name the standard sequences for a region and identify structures in any plane |
| 9 to 10 | Safety and patient care | You can work a screening scenario from the zone rules, not from memory of one facility’s policy |
| 11 to 12 | Timed, full-length practice exams | Two full exams at one minute per question, every miss traced back to the concept |
Studying 8 to 12 hours a week, that is 100 to 140 hours. The week-by-week version, with topics for each block, is in our ARMRIT practice test and study guide; it works for either registry.

Paid review options are easy to find: registry review programs and seminars, question banks with a few thousand items, and review books written in question-and-answer form. Whatever you buy, check it against the current content outline. A question bank written to an older blueprint will over-weight procedures and under-weight image production.
If you do not pass
ARRT gives you three attempts within three years of becoming eligible. Use the score report: it breaks your result down by content area, and the area to fix is almost always image production. Rebuild the physics rather than re-reading questions you have already seen. For ARMRIT, confirm the re-examination fee and any waiting period with the registry directly.
Reviewing for a registry you are not yet eligible for?
Review only helps if you can sit the exam. If you are scanning without a credential, or you work as an aide in an MRI department, eligibility is the first problem to solve.
- No imaging credential yet: an ARMRIT-accredited program plus at least 1,000 documented clinical hours makes you eligible for the ARMRIT exam, and many students log those hours at the site where they already work. See MRI tech aide certification and programs and the ARMRIT certification guide.
- Already ARRT-registered in another modality: MRI is a post-primary credential with structured education and clinical requirements. See the ARRT MRI cross-training program.
Tesla MR students prepare inside the program: coursework mapped to the exam sections, a dedicated registry prep phase, and a timed mock exam before they sit the real one.

Frequently Asked Questions
It is a physics-heavy exam. On the ARRT MRI exam, 106 of the 200 scored questions are image production: physical principles, sequence parameters, data acquisition, and image quality. Candidates who scan every day but have not studied the physics formally are the ones who struggle. Weighting your review toward physics is the single most useful decision you can make.
Start from the official content outline for the exam you are sitting, not from a question bank. Spend the first third of your time on physics and image production, the middle third on procedures and cross-sectional anatomy, then finish with safety and timed practice exams. Review every missed question back to the concept, not the answer.
ARRT allows three attempts within three years of becoming eligible. If you do not pass within that window you have to requalify. ARMRIT sets its own re-examination terms; confirm the current fee and waiting period with ARMRIT when you apply.
ARRT publishes first-time pass rates by discipline in its annual exam statistics, so check the most recent report rather than a number quoted on a review site. ARMRIT does not publish a pass rate. Neither number tells you much about your own odds. Your score on timed, full-length practice exams does.
The ARRT MRI exam has 200 scored questions plus 30 unscored pilot questions. The ARMRIT exam has 225 multiple-choice questions and requires a score of 75 to pass.
Yes. Tesla MR publishes free practice questions with explanations in physics, clinical applications, and safety, plus free cross-sectional anatomy flashcards. ARMRIT's own practice tests are paid: $35 for each 30-question part.
Plan on 10 to 12 weeks at 8 to 12 hours a week if you are fresh out of a program or scanning daily. Give yourself closer to 16 weeks if you work full time or it has been a while since you studied physics.
