Question

Quizplus · Accepted Answer

In an AP clavicle projection with the patient rotated away from the affected shoulder, the medial clavicular end should be shifted away from the vertebral column (2) and the scapular body should have decreased thoracic superimposition (4). This positioning allows for better visualization of the clavicle without overlap from other structures. The other choices, (1) medial clavicular end superimposed over the vertebral column and (3) scapular body with increased thoracic superimposition, would result from incorrect positioning and would hinder proper visualization of the clavicle.
