Self Evaluation - Part 1

Arcot J. Chandrasekhar, M.D. and Ashok J. Kumar, M.D.

 

The following questions test knowledge bites you should have to correctly interpret neuroscience imaging. Continue to take the self evaluation quiz until you have mastered it (90% correct). I will account 10% for difference of opinion. Images and topic content are provided under each chapter.

Note that the examination must be completed in one sitting, so allow yourself enough time. Image based self evaluation exercises will be provided in your clinical years.

This exercise covers questions covering imaging basics, intracranial hemorrhage, CVA and cerebral edema.

This exercise is intended as a self evaluation, teaching and learning tool. Please contact me via email with comments, suggestions or corrections at achandr@luc.edu.
