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).
