I'm toying with the idea of using interactive Flash elements to teach radiology for emergency physicians. It's time intensive to build these modules, but the pay-off may be worth it. What do you think?
I've incorporated this approach to teaching radiology in a few of my past lectures, but I've never done so online. Here is my debut of a Flash-based teaching approach to reading plain films of the wrist.
Roll your mouse over the words to highlight the bones.
Image set #1: Normal xray of the wrist (AP and lateral) with key identifiable structures
Image set #2: Perilunate dislocation For all plain films of the wrist, be sure to look at the lateral view for the 4-bone alignment (distal radius, lunate, capitate, 3rd metacarpal). Oftentimes, dislocations such as this perilunate dislocation are missed.
Image set #3: Lunate dislocation Just yesterday, a Chicago Bears player Brian Urlacher sustained a lunate dislocation, which requires operative repair. Notice that the lunate appears abnormally as a triangle-shape on the AP view, instead of the usual cuboid shape. Furthermore, the lunate has "spilled" volarly on the lateral view. Both perilunate and lunate dislocations place the patient at risk for a median nerve injury.
