Lower Extremity David S. Hartman, M.D. Department of Radiology
Goals • To teach clinically relevant gross anatomy • To make it easier to understand gross anatomy • To introduce a clinical lexicon
Organization • 4 presentations to the entire class • Lower extremity/thorax • Abdomen/pelvis/perineum • Upper extremity/back • Head and neck • Optional review session before each examination
Examinations • 4 radiolgic unknowns on each examination • Images used for the exams are displayed in the lab • Each examination unknown is labeled in PowerPoint
Cases in MDL \\hersheymed.net\files\MMS\Public\education\radiology\lab-thorax-8-2007.pps Cases can be viewed by any computer in the institution
Learning Objectives: Identify all objects indicated by arrows on the radiolgical images in this presentation The same images are on the computers in the lab
