What is a Myelogram?
A myelogram is a diagnostic X-ray procedure performed by a radiologist to detect abnormalities of the spine, spinal cord, and surrounding structures. During the exam, contrast dye is injected into the spinal canal to enhance visualization of nerves and spinal anatomy.
How to Prepare for a Myelogram
A driver is required to drive you home after this procedure. You will not be permitted to drive yourself home after the exam.
Do not eat or drink after midnight before your exam.
This exam requires that you stop taking blood thinners (anticoagulants) before the procedure. Do NOT stop any medication without first speaking with your prescribing provider.
Check with your doctor about all other medications you may be taking.
What Happens During a Myelogram?
You will be placed on your stomach wearing a hospital gown and pants. The lower portion of your back will be cleaned with antiseptic soap, and a local anesthetic will be used.
A lumbar puncture is performed with a needle placed into the spinal canal. A small amount of fluid may be removed and sent to the laboratory. Contrast dye is then injected, and the needle is removed.
The X-ray table will be tilted, and you may be asked to turn from side to side in order to obtain a series of images. After the myelogram, a CT scan will be performed to provide additional detail for the radiologist.
After the CT scan, your head will be elevated 30–45 degrees. Drink plenty of water after the exam to help reduce the chance of a headache.
