What it is

Discography is a test used to determine whether the discs are the source of back pain. It may be performed before surgery to positively identify the painful disc(s).

Spinal discs are soft, compressible discs that separate the interlocking bones (vertebrae) that make up the spine. The discs act as shock absorbers for the spine, allowing it to flex, bend, and twist. Degenerative disc disease can take place throughout the spine, but it most often occurs in the discs in the lower back (lumbar region) and the neck (cervical region).

Before the procedure begins, you will be given antibiotics and relaxation medications through an IV line. Medication is used to numb the skin over the test site. During the procedure, the doctor inserts a needle into one or more discs and injects a contrast dye. You’ll feel pain when the dye is introduced into the problem disc.

Afterward, a CT scan will show any changes in the disc size or shape. You may experience some muscle discomfort after the procedure; your doctor can prescribe pain relievers to ease the discomfort.

No special preparations are required for this test. However, you should not take any pain relievers or anti-inflammatory medications on the day of the procedure.
