2. How is it done?
   
   The patient is given intravenous medication as a relaxant and pain reliever. A local anesthetic is injected into the patient's skin in the area that is being examined.
   
   A needle is inserted through a previously placed needle in the skin and into the disc under fluoroscopy. A saline solution and radiopaque dye are injected into the disc or discs if more than one disc is being examined. A CT scan is usually performed on the painful disc after the dye is injected to obtain images of the dye distribution. This will demonstrate annular tears, scarring, disc bulges and changes in the nucleus of the disc.
