An AP radiograph displays anatomical structures in which direction?

An anteroposterior (AP) radiograph captures anatomical structures in the anterior to posterior direction, meaning it visualizes the body from the front (anterior) to the back (posterior). This imaging technique is commonly used in diagnostic radiology to focus on specific anatomical regions, ensuring that structures can be visualized in a straightforward manner without obstructions from surrounding tissues.

The choice of directions relates to how the patient is positioned and where the x-ray beam enters and exits the body. In an AP view, the x-ray beam passes through the body from the front to the back, which is fundamental for evaluating many conditions and for localizing pathology relative to the body's orientation.

The other answer options do not accurately describe the orientation of structures depicted in an AP radiograph. For instance, lateral directions refer to side views that depict structures with a medial to lateral orientation, while inferior/superior direction would indicate a top to bottom view. Oblique directions would imply an angled view, which is not the case in an AP radiograph.
