Failed MRI registry by 5 points - trying to figure out where I went wrong
Got my results from the ARRT MRI registry exam last week and I scored a 78 when you need an 83 to pass. I'm pretty frustrated because I felt okay coming out of it — not confident, but okay. Now I'm trying to figure out what to do differently for my retake in 90 days.
Looking at the domain breakdown, physics and instrumentation killed me. I knew that was going to be my weak area going in and I spent a lot of time on it, but clearly not enough or not the right kind of studying. Patient care and safety I did well on, which makes sense since that's closest to my daily work as an RT. The imaging procedures section was somewhere in the middle — I think I was getting tripped up on sequences and protocols for neurological imaging specifically.
I studied for about 12 weeks total, using Westbrook's MRI in Practice as my main text plus a question bank I found online. I did about 600 practice questions total. Part of my problem might be that I was doing questions but not really learning from the wrong ones — I'd see the correct answer and move on without drilling into why it was right. That's definitely changing for my retake.
Anyone else retake this and pass the second time? I'm wondering if the physics content is actually as different between attempts as some people say or if I'm just going to see similar concepts in a different order. Also curious whether anyone found a Brant and Helms review useful versus focusing just on the ARRT content outline.
Failed my first attempt by 3 points and passed my retake with an 86. The physics content does vary somewhat between attempts but the core concepts repeat — magnetic field homogeneity, k-space filling, gradient behavior. What helped me most was drawing out the concepts rather than just reading about them.
Brant and Helms is more radiology-broad than MRI-specific — I'd stick with Westbrook plus the ARRT content outline and make sure you're covering every bulleted item in the physics section. There are about 12-15 concepts in there that I'd bet will show up in some form.
90 days is enough time if you're focused. I'd commit to 60-90 minutes every day rather than marathon weekend sessions. The physics stuff really does need spaced repetition to stick — I used Anki cards for anything related to gradient echo versus spin echo mechanisms and it helped a lot.
The wrong-answer review habit is huge. I failed partly for the same reason — I was racking up question volume without retaining why I was wrong. On my second attempt I kept an error log and reviewed it every Sunday. Went from a 79 to an 85 on the retake.
