摘　　要：目的探讨腰椎间盘突出症化学微创治疗前后CT影像变化与临床疗效的相关性,为治疗结果提供影像学依据。方法对经胶原酶和臭氧微创介入治疗前后有完整CT复查资料的33例腰椎间盘突出症患者的38个椎间盘突出物,进行前后径和CT值测量,对所得数据采用统计学配对设计分析。结果 38个椎间盘突出物CT值减低最多为53Hu,最少为-8Hu,平均减低10.7Hu,经秩和检验P=0.0000<0.0500,差异有统计学意义。突出物前后径缩小最多7.5 mm,最少为-0.5 mm,平均缩小1.28 mm,经秩和检验P=0.0000<0.0500,有统计学意义。结论化学微创治疗(尤其是胶原酶和臭氧联合治疗)后腰椎间盘突出物的缩小和CT值的减低在一定程度上为治疗效果提供了影像学依据。Objective To investigate the relation between the clinical effect and the changes of CT images after the chemical minimally invasive treatment of lumbar disc herniation,and further more to provide the imaging evidence for the treatment.Methods 38 waist intervertebral discs of 33 patients with intact CT review data who were treated by the minimally invasive treatment of collagenase and ozone were measured by anteroposterior diameter and CT value.The data were statistically analyzed by t test or rank test for paired data.Results The reduction of CT values of 38 cases were ranged from-8Hu（Min）to 53Hu（Max）,and the average of that was 10.7Hu（P=0.00000.0500）.The reduction of the anteroposterior diameters of protrusions were ranged from-0.5 mm（Min）to 7.5mm（Max）,and the average of that was 1.28mm（P=0.00000.0500）.All data were analyzed by rank test and the differences were statistically significant.Conclusion To some extent,the reduction of anteroposterior diameters of lumbar disc herniation and CT value after chemical minimally invasive treatment（especially that of collagenase and ozone）can provide the imaging evidence for the treatment.
