A simple and entertaining radiology learning medical app was just released by Dr. Elliott Fishman and colleagues at Johns Hopkins called CTisus 10 minute ER Challenge. The two authors listed for the 10 minute ER Challenge app are Pamela T. Johnson MD and Elliott K. Fishman MD. Both are faculty members at Johns Hopkins.

The radiology learning app presents 60 cases and gives you 10 seconds to respond to each case before giving you the answer — that’s where the “10 minute challenge” comes into play.

10 minute ER challenge

The 10 minute ER challenge app does not give case based presentations or multiple choice options — this isn’t a comprehensive app for learning emergency radiology imaging — that’s not the point. The app is free to download, and it’s apparent the developers wanted to create a simple radiology learning app that just worked.

This radiology learning app is simple enough to use while on shift or even if you’re waiting in line for your coffee.

What providers would benefit from the CTisus 10 minute ER Challenge medical app?

Emergency room physicians, trauma surgeons, clinicians who work in urgent care offices.
