Discography was first performed in 1948 by the Swedish radiologist K. Lindblom, who injected red lead contrast into cadaveric intervertebral discs (IVDs), to diagnose discal degenerative changes (1). At the beginning of the 21st century, discography is sometimes used as a diagnostic technique, mainly when computed tomography (CT), magnetic resonance (MR), or myelography is equivocal. It is followed, when possible, by CT examination (CT discography). Presently, however, discography is most often carried out as the first step of an operative procedure such as chemonucleolysis, intradiscal radiofrequency or laser therapy, or intradiscal injection of steroids or anesthetics.
