Quizplus · Accepted Answer

The AP scapular projection with accurate positioning should demonstrate almost superimposed anterior and posterior glenoid fossa margins (1), the humeral shaft at a 90-degree angle with the body (3), and the supraspinatus fossa and superior scapular angle without clavicular superimposition (4). However, the vertebral scapular border may have some thoracic cavity superimposition (2) and is not a crucial criterion for accurate positioning. Therefore, the correct choice is B, which includes options 1, 3, and 4.
