Abstract: Objective To analyze the imaging manifestations and clinical comparison of the localized high-signal area of lumbar disc MRI, so as to improve the clinical significance of this sign. Methods Retrospective analysis of 35 patients with low back pain associated with lumbar disc MRI localization high signal area imaging characteristics were analyzed, diagnosis, clinical data and surgical pathology control. Results MR sagittal T2WI images in the localized high signal area of lumbar disc MRI were round （71.4%）, arc-shaped （20.0%） or radial （8.6%）. The axial image was striate or fusiform, consistent with the annulus rupture of intervertebral disc. The location of the high signal is consistent with clinical symptoms. Conclusion The localized high signal area of LUMBAR disc MRI has a certain specificity for the diagnosis of lumbar intervertebral disc low back pain. The presence of this sign may indicate disc annulus tear and provide reference for the diagnosis and treatment of patients with low back pain.
