This is the only comprehensive review system that exists. While it may not teach you everything, it teaches you what you need to PASS and be comfortable.

I would like to thank you for writing and continually updating crack the core and war machine. I would be a worse radiologist and would not have passed the core without these books. Your sense of humor and straight to the point explanations are greatly appreciated. For the sake of future residency classes, please continue fighting the good fight.

Crack the Core is essential to passing the Core exam. Every resident at my institution used it as their primary resource for both the imaging diagnosis and physics portions of the exam. I felt as prepared as I could have been thanks to Prometheus and his resources. These books will be useful far past the core exam, and I’ve seen many fellows that come from outside programs frequently referencing it. Thanks Prometheus, I couldn’t have done it without you.

It’s difficult to have a perfect study source for a wide subject like Radiology, but this is certainly pound for pound the BEST resource available!

THANK YOU for your enthusiasm and effort! By far the easiest videos to sit through – your sense of humor was MUCH appreciated, and helped immensely when trying to suffer through otherwise mundane material (i.e. “Non-interpretive skills”).
