American Society of Radiologic Technologist (ASRT) Practice Exam

The lateral view is specifically used to visualize the spine in its lateral position. In this orientation, the x-ray beam is directed from one side of the body to the other. This position allows radiologists to assess the alignment of the vertebrae, identify any abnormalities such as fractures or scoliosis, and examine intervertebral discs. The lateral view is particularly beneficial for viewing the curvature and overall anatomy of the spine as it provides a clear profile image.

This is in contrast to other views like the AP (anterior-posterior) view, which visualizes the spine from the front, or the oblique view, which is angled to provide a perspective that visualizes the side and between the vertebrae at a diagonal angle. The axial view, on the other hand, usually refers to imaging obtained from a plane that is horizontal and may not be specifically focused on a side profile of the spine. Thus, the lateral view is the most effective in providing detailed imaging of the spine's structure from the side.
