Which view is used to identify lateral and medial locations?

• A. LAO
• B. RAO
• C. AP
• D. PA

Answer: (A)

The left anterior oblique projection is used to identify lateral versus medial locations because rotating the patient into an oblique view separates structures that are overlapped in a frontal view. By bringing the left side toward the detector and positioning it anteriorly, the left-sided structures are moved away from the spine and sternum, making the lateral surfaces easier to distinguish from the medial ones. Straight AP or PA views tend to overlap left and right structures and don’t provide the same clear separation, while a right anterior oblique view would emphasize the opposite side. So the oblique left anterior orientation best clarifies which parts are lateral versus medial.
