1 Lower Extremity David S. Hartman, M.D. Department of Radiology

2 Goals 1.To teach clinically relevant gross anatomy 2.To make it easier to understand gross anatomy 3.To introduce a clinical lexicon

3 Organization 1.4 presentations to the entire class 1.Lower extremity/thorax 2.Abdomen/pelvis/perineum 3.Upper extremity/back 4.Head and neck 2.Optional review session before each examination

4 Examinations 1.4 radiolgic unknowns on each examination 2.Images used for the exams are displayed in the lab 3.Each examination unknown is labeled in PowerPoint

5 Cases in MDL \\hersheymed.net\files\MMS\Public\education\radiology\lab-thorax pps Cases can be viewed by any computer in the institution

6 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
