ABSTRACT
<p><b>OBJECTIVE</b>To study correlation between high intensity zone (HIZ) of lumbar disc and positive pain response on lumbar discography for the diagnosis and treatment of discogenic low back pain.</p><p><b>METHODS</b>Thirty-seven cases with chronic low back pain without neurologic symptoms and lumbar disc herniation on CT scan underwent lumbar discography and MRI examination. X-ray and CT after discography with positive pain response were analyzed to correlate with HIZ on MRI.</p><p><b>RESULTS</b>Ninety-eight discs underwent discography in 37 patients. Twenty-one discs presented positive pain response; including 10 have HIZ (47.6%). Seventy-seven discs presented negative pain response; including 29 had HIZ (37.6%). The higher grade of annular disruption group had the higher proportion of HIZ on lumbar MRI. There was a positive correlation between HIZ and degree of annular disruption. However, there was no correlation between HIZ and positive pain response on lumbar discography.</p><p><b>CONCLUSIONS</b>HIZ on lumbar MRI only can be a filtrated and suggestive image sign and can not replace discography in the diagnosis and treatment of discogenic low back pain.</p>
