For the three AP axial projection of the cervical spine, which direction should the tube be angled and by how many degrees?

• A. Caudal; 15 to 20°
• B. Cephalic; 15 to 20°
• C. Cephalic; 25 to 30°
• D. Caudal; 20 to 25°

Answer: (B)

For the AP axial projection of the cervical spine, the x-ray tube should be angled cephalically at an angle of 15 to 20 degrees. The purpose of angling the tube in this manner is to project the cervical vertebrae away from the shoulders, which helps to reduce superimposition of the shoulder over the upper cervical vertebrae, allowing clearer visualization of the cervical spine. Proper angulation is crucial in ensuring optimal image quality and diagnostic efficacy, facilitating accurate assessment of conditions affecting the cervical spine. The range of 15 to 20 degrees is effective in achieving this goal.
