2. Abdomino-Pelvic (AP) Region: Denotes the area of the abdomen and pelvis, relevant in imaging and diagnostic studies of this anatomical region.
3. Acetabular Protrusio (AP): A condition seen on radiographs where the acetabulum is abnormally displaced medially, often used in the context of hip joint imaging.
