CAMRT Radiography Practice Exam

What is demonstrated on an oblique view of a Myelogram?

1. Herniated discs

2. Ruptured intervertebral discs

3. Spinal stenosis

4. Bone spurs

The correct answer is: Ruptured intervertebral discs

An oblique view during a myelogram is particularly effective in demonstrating the presence and condition of intervertebral discs. Myelography involves the use of a contrast dye injected into the spinal canal, which enhances the visualization of structures in the spine using imaging techniques such as X-ray or CT scans. When focusing on the intervertebral discs specifically, an oblique view allows for a clearer assessment of how the discs are positioned and whether there are any protrusions or ruptures. A ruptured disc typically shows a distortion in the normal profile of the disc, and the contrast material helps to reveal any leakage or herniation affecting surrounding nerves. This view is particularly relevant because, while other conditions such as herniated discs and bone spurs may also be visible, for detecting and assessing ruptured intervertebral discs, the oblique angle provides a definitive perspective that enhances diagnosis. The visibility of the altered disc contour and the potential nerve compression due to the rupture is typically more pronounced in this view, making it the preferred choice for this specific assessment.
