Abstract

Abstract: The purpose of this study was to explore the diagnostic value of CT in lumbar disc herniation and the positioning significance of radiofrequency ablation. 103 patients with lumbar disc herniation were selected and given CT examination and CT-guided radiofrequency ablation. The experimental results showed that the accuracy rate of CT examination in the diagnosis of lumbar disc herniation was 90.29%.The proportion of hill-shaped protrusion, nerve root compression or adhesion in severe patients were higher than those in mild to moderate patients (P<0.05), the sagittal diameter and anterior-posterior diameter of dural sac were lower than that of mild to moderate patients (P<0.05).The areas under ROC curve predicted by sagittal diameter and anterior-posterior diameter of dural sac in severe patients were 0.866 and 0.848, respectively (P<0.05). The proportion of hill-shaped protrusion, nerve root compression or adhesion in patients with excellent curative effect were lower than those in patients with non-excellent curative effect (P<0.05), the sagittal diameter and anterior-posterior diameter of dural sac were higher than that of non-excellent patients (P<0.05). This study confirmed that CT has a high value in the diagnosis of lumbar disc herniation, and the effect of CT-guided radiofrequency ablation is good.
