3)left zygapophyseal joints.
4)vertebral column superimposed over the right SC joint and medial clavicle.

Question

Quizplus · Accepted Answer

A PA axial oblique cervical projection (LAO position) obtained with the patient overrotated will show the right pedicles in profile because they will be projected away from the vertebral bodies. Additionally, the left zygapophyseal joints will be demonstrated, as they are closer to the IR in this view. The vertebral column will not be superimposed over the right SC joint and medial clavicle in this projection because the patient is overrotated, which shifts the vertebral column away from those structures. The right pedicles will not be in the midlines of the vertebral bodies for the same reason.
