myelogram
Spinal canal X-ray
A myelogram is a diagnostic X-ray image of the spinal canal, taken after injecting contrast dye into the spinal fluid.
The procedure reveals abnormalities in the spinal cord, nerve roots, or surrounding structures that ordinary X-rays can't detect: The myelogram showed a herniated disc pressing on the nerve.
Largely replaced by MRI scans but still used when MRI is contraindicated.
