As I was driving to work this morning, I heard this very interesting news article from NPR by Alix Spiegel.   Since this my profession, I can easily understand how easy this would be to do.   We can sometimes be going through 1000s of images/per patient with the some of the more advance cross sectional imaging modalities.  PET and CT scans are commonly fused now and we are now looking at sections of the human body in all three planes.   Given the complexity and number of images it would be very easy to miss the gorilla hiding in plain sight.  Click the play button below to listen to the NPR piece.  I also included the original video regarding the gorilla.
