CAMRT Radiography Practice Exam

What aspect of a patient's positioning is crucial in demonstrating the appropriate side during an L-spine oblique?

1. The distance from the receptor

2. The level of the iliac crest

3. The side closest to the imaging receptor

4. The angle of the x-ray beam

The correct answer is: The side closest to the imaging receptor

In demonstrating the appropriate side during an L-spine oblique examination, the side closest to the imaging receptor is critical. This positioning ensures optimal visualization of the targeted anatomy, particularly the facet joints and the intervertebral foramina. When the patient is positioned appropriately, with the side of interest nearest to the receptor, it allows for a clearer image by minimizing geometric distortion and maximizing the detail captured for diagnostic purposes. The other aspects, while they may influence the overall quality of the radiograph, do not directly determine the side being demonstrated. The distance from the receptor can affect image sharpness but does not specifically highlight the side of interest. The level of the iliac crest is important for overall alignment and centering but again does not dictate which side is emphasized in the view. The angle of the x-ray beam is crucial for the projection and can change the appearance of the anatomy, but the fundamental positioning of the patient remains the most important factor for correctly demonstrating the side in an oblique view.
