AP View of the Wrist

- See:
- PA View
- Radial Inclination
- Discussion:
- AP has the dorsum of the hand touching the film, with the x-ray beam passing palmar to dorsal, whereas in a PA film, the palmar surface lies flat on the film and the x-ray beam passes from the dorsal to palmar surface;
- palmar surfaces of most carpal bones are narrower, and therefore are best seen w/ an AP projection because of the alignment of the peri-articular cortices with the diverging incident x-ray beam;
- position of the ulnar styloid will determine which way film was taken;
- in standard PA view, the ulnar styloid is peripheral;
- in the standard AP position, the ulnar styloid points centrally
