NORMAL MAGNETIC-RESONANCE-IMAGING AND ABNORMAL DISCOGRAPHY IN LUMBAR DISC DISRUPTION

Study Design. This report describes a clinical series of seven patient s who had surgically proven internal disc disruption, normal magnetic resonance imaging, and abnormal discograms morphologically. Summary of Background Data. Numerous reports in the literature have described th e utility of magnetic resonance imaging and discography in diagnosing degenerative disease within lumbar intervertebral discs. Results. Disc ography may be useful in patients with persistent symptoms despite a n ormal or equivocal magnetic resonance imaging study.
