Question: 1 / 400

What is a myelogram?

A scan of brain functionality

An injection of contrast into the esophagus

An imaging examination of the spinal cord

A myelogram is an imaging examination specifically designed to visualize the spinal cord and the surrounding structures. During this procedure, a contrast dye is injected into the epidural space of the spine, often through a spinal tap. This enhances the visibility of the spinal cord and nerve roots on X-ray or CT scans, allowing healthcare professionals to identify any abnormalities such as herniated discs, tumors, or spinal stenosis.

The method is particularly useful in diagnosing conditions that affect the spinal cord and can help guide further treatment options based on the findings. The use of contrast material is crucial, as it improves the contrast of images, making it easier to interpret and assess any potential issues related to the spinal cord.
