Diskography is an imaging test. It involves injecting a contrast material into a disk in the spine and taking an x-ray . An x-ray is a test that uses radiation to take a picture of structures inside the body. The contrast material helps the disk appear more clearly on the x-ray.

This test is used to detect a herniated disk . This occurs when a disk in the spine bulges from its proper place. Disks are small, circular cushions between the vertebrae (bones) in the spine. Herniated disks can press on the nerves and cause severe pain.
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:
- Nerve injury
- Injection of dye into the wrong area
- Allergic reaction to the contrast agent
Call Your Doctor
After the test, call your doctor if any of the following occurs:
- Signs of infection, including fever and chills
- Severe pain
- Numbness in your legs
- Trouble urinating or moving your bowels
- Symptoms of allergic reaction (eg, hives , itching, nausea, swollen or itchy eyes, tight throat, difficulty breathing)
- Worsening of your symptoms
In case of an emergency, CALL 911.
