ACR introduces the ACR Case Challenge. The ACR Case Challenge is a knowledge game based on ACR's popular Case in Point.

The ACR Case Challenge allows you to play against your friends on a variety of radiology topics while improving your knowledge in specific areas of radiology. This game is an add-on to the highly popular Case in Point on the ACR Web site.

Everyday a new case will appear on the ACR Case Challenge. You score points for each correct answer. Your aggregate score is kept along with your friends' scores and after completing the Challenge you will be taken to the leaderboard. The leaderboard will show the top 10 Case Challenge players. If you are not in the top 10, you will have your personal score shown to you, which includes your percentile ranking.

Each case is active for only one day and you cannot go back to take previous Challenges. Each correct answer given is worth one point and the rankings are determined by the highest number of points. Make sure you go each day to complete the Challenge to move up the leaderboard.

The cases in the Case Challenge are based on Case in Point content. Take the Challenge first. At the end of the Case Challenge, on the leaderboard page, click the Case in Point icon. This takes you to the daily Case in Point, where you can read the full content including explanations, case findings, case points, discussion and references to complete the learning experience.
