Clover Learning Radiography Positioning For The Spine Practice Test

What rotation angle is typically used for a cervical oblique projection and what is assessed?

About 30 degrees; assesses anterior arch About 45 degrees; assesses zygapophyseal joints About 60 degrees; assesses spinous processes About 15 degrees; assesses vertebral bodies

Correct Answer:

About 45 degrees; assesses zygapophyseal joints

Explanation:

Rotating the patient about 45 degrees during a cervical oblique projection places the plane of the zygapophyseal (facet) joints in profile and aligned with the image receptor, which is essential for evaluating those joints. This oblique angle opens the facet joint spaces between the superior and inferior articular processes, allowing assessment of alignment and potential degenerative changes. The other angles don’t optimize visualization of these joints: too little rotation tends to show mainly the vertebral bodies and spinous processes, while too much rotation can obscure or distort the facet joints. The purpose of the cervical oblique view is specifically to assess the zygapophyseal joints rather than the anterior arch, spinous processes, or vertebral bodies.
