Train for the 3 a.m. read.

Emergency Radiology is a free trainer for the can't-miss cases you meet on call. You read real CT and MRI in a proper viewer, defend your call across five modes, and watch your weak spots shrink — built entirely on openly-licensed data.

How it works

Every case can be drilled five ways: spot the finding on the scan, pick the diagnosis, build a differential + next step, dictate a report and compare to a model read, or take the hot-seat call. Learn is a concise atlas of the same cases; your dashboard tracks mastery, accuracy, streaks and a personal miss-tracker.
