PA hand  

The PA (posteroanterior) view is obtained in any radiologic examination of the hand and wrist. Since the human thumb is "rotated" 90° with respect to the fingers, this radiograph gives an oblique view of the thumb, but a PA view of all other structures. This shows a magnified view of the carpals.
