A myelogram is a radiographic procedure that involves the injection of contrast material into the subarachnoid space (the space around the spinal cord) by a Radiologist. A myelogram allows the radiologist to detect pathology of the spinal cord, nerve roots, and meniges, (membranes which surround and cover the spinal cord and nerve roots.) The radiologist will inject the contrast material using fluoroscopy to watch the flow of contrast, real time as it passes through the spinal canal. A certified, highly skilled technologist will be with you during the entire procedure, assisting in moving from side to side to allow the contrast to flow appropriately. Once the contrast is in place, the technologist will take a series of X-Rays in various positions. In most cases, a CT Scan is performed immediately following the myelogram to better visualize the anatomy and any abnormalities.
Your physician will give you detailed instructions for your myelogram. Please inform your physician of any medications you are taking as well as any allergies you may have. Also inform your physician regarding a recent illness or other medical conditions.
Women should inform their physician if they are pregnant, or if there is any possibility they may be pregnant.
Radiation Dose: Special care is taken during X-Ray examinations to use of the lowest radiation dose possible while producing the best images for evaluation.
