Quizplus · Accepted Answer

In an AP axial cervical projection, the patient is rotated to one side to visualize the intervertebral foramina on the opposite side. By rotating towards the right side, spinous processes will be positioned closer to the left side of the vertebral bodies (1). Closed intervertebral joint spaces (2) may be due to improper exposure factors or due to osteophytes leading to narrowing of joint space. Elongation of uncinate processes (3) will be better visualized on the side opposite to the rotation. The left SC (superior articular process of the cervical vertebra) will be superimposed over the vertebral column (4).
