Question: 1 / 1100

During a lumbar spine examination, what does the term "oblique" refer to?

The angle of the x-ray beam

In the context of a lumbar spine examination, the term "oblique" refers specifically to the angle at which the x-ray beam is directed. When performing oblique views of the lumbar spine, the x-ray beam is angled, usually between 45 and 70 degrees, relative to the patient's body. This positioning is crucial because it allows for visualization of the intervertebral foramina and the zygapophyseal joints, which may not be clearly seen on standard AP (anterior-posterior) or lateral views.

The oblique view helps to project anatomical structures that would otherwise superimpose on one another in standard views, thereby providing a clearer image of the lumbar spine's anatomy for diagnostic purposes. Adjusting the angle of the x-ray beam in this way allows radiologists and physicians to assess potential conditions such as herniated discs, spondylolisthesis, or fractures more effectively.
