5. Familiarize yourself with cross-sectional anatomy of the abdominopelvic cavity as it pertains to ‘spatial relationships between organs, vessels and nerves in order to interpret scans and radiographs of the normal anatomy of these regions. Identify and use landmarks to navigate CTs and MRIs.

   - Intestinal Resection, Ulcerative Colitis, Appendicitis; Appendectomy, Rebound Tenderness, Referred Pain, McBurney Point, Peritonitis, Gallstones, GB pain, jaundice, Cholecystectomy, Colostomy, Diverticulitis
