Discogram Definition

Discogram is a procedure used to determine the anatomical source of a patient's low back pain. The discographer inserts a needle in the patient's back into the center of the disc. Radiographic dye is then injected into the disc. If injecting the dye recreates the patient's normal pain (concordant), it is then inferred that the specific disc is the source of pain for the patient.

This procedure is most frequently used to determine if degenerative disc disease is the cause of a patient's pain (discogenic low back pain).
