Which diagnostic study demonstrates a herniated disc causing spinal compression?

• A. Electromyogram
• B. Myelogram
• C. Cross-table x-ray
• D. Angiography

Answer: (B)

The myelogram is the diagnostic study of choice for visualizing a herniated disc that may be causing spinal compression. This procedure involves the injection of a contrast medium into the subarachnoid space of the spinal canal, which allows for enhanced imaging of the spinal cord and nerve roots when combined with X-ray or CT imaging. The contrast helps to delineate the anatomy and pathologies such as herniated discs, tumors, or spinal stenosis that might be affecting the spinal structures. By providing clear images of the spinal canal and surrounding areas, a myelogram can help identify the exact location of the herniation and the extent of any compression on the spinal cord or nerves, aiding in diagnosis and treatment planning. This specificity makes it a valuable tool in the evaluation of back pain related to disc issues. Other imaging techniques may provide useful information but do not offer the same level of detail regarding soft tissue structures, which is crucial in such cases.
