Diskography is an imaging test. It involves injecting a contrast material into a disk in the spine and taking an x-ray
This test is used to detect a herniated disk
Complications are rare, but no procedure is completely free of risk. If you are planning to have diskography, your doctor will review a list of possible complications, which may include:
Your doctor may do the following:
Your doctor may instruct you to:
You will lie on your side on a table. A technician will help place you into position. You may be given antibiotics through an IV. You may receive an injection of local anesthetic into the skin on your back. This will be done to reduce pain from the needles.
Your doctor will use an imaging test called fluoroscopy. It combines x-ray technology with a TV screen to help guide needles into the disks. A contrast dye will be injected into the center of each disk. If the disk is normal, the liquid will remain in the center of the disk. If it is abnormal, the x-ray will detect any leaks.
During the exam, you will be asked to rate any pain that is associated with the injections. This can help your doctor find out if it is the abnormal disk that is causing pain. After this test, your doctor may do a CT scan to see the spread of the contrast dye.
The staff will observe you for 30 minutes or more.
If you took a sedative, do not drive, operate machinery, or make important decisions until the sedative wears off.
About 30-45 minutes (an additional 30-60 minutes if a CT scan is also done)
You may have pain from the contrast dye. Pain can last for several hours.
The results will be given to your doctor. Your doctor will talk to you about the results and treatment options.
After the test, call your doctor if any of the following occurs:
