To obtain open intervertebral disk spaces for AP axial cervical vertebrae projections when imaging the upright and kyphotic patient, the central ray
A) should remain horizontal.
B) angulation needs to be decreased over that used on the supine patient.
C) angulation needs to be increased over that used on the supine patient.
D) should be angled caudally.

Question

Quizplus · Accepted Answer

When imaging the upright and kyphotic patient, the disk spaces in the cervical vertebrae are closer together than when the patient is supine. Therefore, to obtain open intervertebral disk spaces for AP axial cervical vertebrae projections, the central ray should be angled more superiorly than that used on the supine patient. Therefore, angulation needs to be increased over that used on the supine patient.
