An AP radiograph displays anatomical structures in which direction?

Explanation:
Projection direction in radiography is determined by the path of the X-ray beam. In an AP projection, the beam travels from the anterior (front) to the posterior (back), so the image displays anatomy in the anterior-to-posterior direction. The patient is positioned with the front toward the X-ray tube and the back toward the detector, which is why structures appear in a front-to-back order on the radiograph. Lateral directions (left-right), inferior/superior (up-down), and oblique planes describe other kinds of orientation, not the AP projection’s beam path. Therefore, an AP radiograph shows structures in the anterior-posterior direction.
