CAMRT Radiography Practice Exam

What are oblique cervical spine views primarily used to assess?

1. Vertebral fractures

2. Thoracic outlet syndrome

3. Zygapophyseal joints

4. Cervical disc herniation

The correct answer is: Zygapophyseal joints

Oblique cervical spine views are primarily utilized to assess the zygapophyseal joints, which are the facet joints located between the vertebrae in the cervical spine. These joints play a crucial role in facilitating the movement and stability of the spine. The oblique view allows radiologists to visualize the joints from an angle that provides clearer information about their condition, including any potential degeneration, arthritis, or misalignment. In contrast, while vertebral fractures can be assessed through various imaging techniques, they are typically more directly evaluated with standard AP and lateral views. Thoracic outlet syndrome is addressed through a combination of physical exams and other imaging techniques that focus on the shoulder and upper chest area, not primarily through cervical spine views. Similarly, cervical disc herniation is more accurately diagnosed through MRI or other imaging modalities that give a clear view of the intervertebral discs and surrounding structures, rather than relying on oblique views focused on the zygapophyseal joints.
