Lumbar or cervical discogram is a pre-surgical diagnostic study used to determine if your pain is generated by a disc. The study is designed to provide a pain "road map" and can help your doctor decide whether or not surgery is necessary. You will be given light sedation and x-ray guidance will be used to assure accurate placement of the needle. After proper placement has been established, x-ray contrast is injected into the disc. The pressure in the disc is monitored and recorded during the injection. A report will be sent to your physician as soon as possible and a recommended course of treatment will be decided by your referring physician.
