1) To review classic signs of neuroradiology to aid in the recognition and interpretation of imaging findings. 2) To add fun to the learning process by introducing competitiveness in a game format and where possible adding related pictures to named signs (example: showing a real hot cross bun with the 'hot cross bun' sign of multi system atrophy)

20 classic signs in neuroradiology will be depicted on Microsoft Powerpoint using a format similar to the game 'Jeopardy'. There will be 4 levels of difficulty: R1/R2 for first and second year residents, R3 for third year residents, R4 for fourth year residents, and R5 for fifth year residents. Delegates evaluating these cases will be able to score themsevles with a point system based on the level of difficulty. Every answer will lead to a list of two to three questions for bonus points.

Classic radiologic signs described in literature, when invoked immediately bring an impression of the image in mind, giving us a confidence in diagnosis. Familiarity of the signs and the game format will introduce some fun into the learning process.
