CAMRT Radiography Practice Exam

When performing a C-spine oblique, which side is of interest?

1. The side farthest from the tube

2. The side closest to the tube

3. The side of the injury

4. Both sides equally

The correct answer is: The side closest to the tube

In a C-spine oblique view, the side closest to the x-ray tube is of primary interest because this positioning technique is designed to project the structures of interest away from the vertebrae, reducing superimposition and enhancing visibility. By angling the x-ray beam towards the closest side, the relevant foramina and neural foramina become clearer and are better visualized in the resulting images. This technique allows for more accurate assessment of possible pathologies or injuries that may be affecting the cervical spine on the observed side. The other considerations, while clinically relevant, do not determine the side of interest in this particular view. For instance, while it might seem logical to focus on the side of the injury, the oblique positioning and the resultant image quality ultimately depend on the angulation towards the side nearest to the tube. This choice maximizes the diagnostic value of the images captured during the examination.
