Which intervertebral foramina are demonstrated on the AP axial oblique projection of the cervical spine?

The correct choice is the intervertebral foramina that are farthest from the image receptor (IR) are demonstrated on the AP axial oblique projection of the cervical spine. In this projection, the patient is typically positioned at an angle, which allows for a better view of the foramina that are situated away from the side closest to the IR.

When performing the AP axial oblique projection, the x-ray beam is angled and directed towards the foramina on the side that is opposite the IR. This angling and positioning illuminate the farthest foramina clearly, making them visually distinct on the radiograph. This is a fundamental practice in radiology to enhance the visibility of specific anatomical features while minimizing superimposition from surrounding structures.

Understanding this projection's orientation is crucial for adequately demonstrating the cervical intervertebral foramina, aiding in the diagnosis of pathologies affecting the neural structures contained within.
