What is a myelogram used for?

A myelogram is utilized specifically to evaluate the spinal cord and nerve roots through the use of contrast dye. This imaging procedure helps to enhance the visibility of these structures on X-rays or CT scans. By introducing contrast material into the spinal canal, physicians can obtain clearer images that allow for the identification of abnormalities such as herniated discs, tumors, or inflammation that may be pressing on the spinal cord or nerve roots.

In contrast, the other options do not accurately describe the function of a myelogram. Detecting fractures in bones involves imaging techniques like X-rays or MRIs rather than a myelogram. Assessing muscle strength is a clinical evaluation performed through physical examination and does not require imaging techniques. Measuring spinal disc height is typically done through imaging modalities like MRI but not specifically through a myelogram, which focuses more on the impact of conditions on the spinal cord and nerves rather than the physical characteristics of the discs themselves.
