What is the standard patient position for an AP thoracic spine radiograph?

• A. Upright or Supine
• B. Prone
• C. Lateral
• D. Seated

Answer: (A)

For an AP thoracic spine radiograph, the patient is positioned either upright (standing) or supine. This approach keeps the spine aligned with the image receptor and minimizes distortion, allowing a consistent view of vertebral bodies and alignment. An upright position also uses gravity to place the spine in a natural posture, facilitating evaluation of any deformities or instability. If standing isn’t possible due to injury or illness, a supine position provides a stable, reproducible projection with minimal motion. Prone would alter the thoracic curvature and trunk orientation, making the AP view less representative, while a lateral view is a different projection entirely. Seated can be considered a form of upright, but the standard phrasing is upright or supine.
