A discogram is a radiodiagnostic study used to determine the structural integrity of a disc and whether a particular disc is responsible for pain. Before the Discogram Preparation for the discogram includes the following: Allergy and medication history must be reviewed with the physician prior to scheduling a discogram. Patients must have an escort on the day of this procedure and must be fasting from 12:00 midnight prior to the procedure. What to Expect During a Discogram In general, discograms follow this process: An IV line is inserted to allow for the administration of medication for sedation and/or pain relief. A spinal needle is guided under fluoroscopy (X-ray) into the disc that is suspected of causing pain. A radiopaque dye is injected through the spinal needle into the disc. The doctor observes the dye pattern for leakage outside the disc walls. At this point, the patient is questioned regarding the similarity of this pain to the usual pain experienced. If necessary, pain medication will be given intravenously. A CT Scan may be performed following the procedure to further study and document the results. Patients may be discharged when fully recovered from the effects of any medications administered during the procedure. The total time required for this procedure is as follows: discogram (45 minutes), CT Scan (30 minutes), recovery time (1-2 hours).
