CT Scan Myelogram
Understanding CT Scan Myelogram
What is CT Scan Myelogram?
The CT Scan Myelogram is a special imaging test used to examine the spinal cord, nerve roots, and the spinal canal. It combines a myelogram (which involves injecting a contrast dye into the space around the spinal cord) with a CT scan, which takes detailed cross-sectional images of the spine.
This test is often recommended when an MRI is not possible or doesn’t provide enough detail, especially in cases of back pain, numbness, tingling, leg or arm weakness, or suspected disc herniation, spinal tumors, spinal stenosis, or nerve compression.
During the procedure, a contrast dye is injected into the spinal canal using a thin needle, usually in the lower back. After the dye spreads, a CT scan is performed to capture detailed images. The test is generally safe, but you may experience temporary headache, nausea, or discomfort at the injection site. Let your doctor know if you have allergies, kidney problems, or if you are pregnant before undergoing this test.
What is CT Scan Myelogram used for?
- To assess the structure of the spinal column, spinal nerve roots, and spinal lining or meninges
- To diagnose any suspected infections and inflammations of the spinal column
- To detect any tumors (abnormal growth) of the spinal column
- To detect the lesions or other damage to the spinal column due to trauma
- To evaluate many diseases, including herniated discs (discs that bulge and press on nerves and/or the spinal cord), spinal stenosis (degeneration and swelling of the bones and tissues around the spinal cord that make the canal narrow) and ankylosing spondylitis (a disease that affects the spine)
- To diagnose the presence of cysts (benign capsules that may be filled with fluid or solid matter)
