Y1 - 2016 N1 - T2 - Principles and Practice of Pain Medicine, 3e AB - Discography is a diagnostic test in which radiographic contrast is injected into the nucleus pulposus of the intervertebral disc. Although originally developed for the study of disc herniation, discography is now used most commonly to identify symptomatic disc degeneration. There are two components of discography: (1) the anatomic appearance of contrast spread within the disc (using plain radiographs and/or computed tomography [CT]) and (2) the presence or absence of typical pain during contrast injection within the disc (pain provocation).
