摘　　要：目的:探讨MRI对腰椎间盘脱出髓核游离的诊断价值。方法:回顾性分析本院2014年7月-2015年10月经手术证实的20例腰椎间盘脱出髓核游离患者的临床及影像学资料。结果:20例患者中,髓核向上移位10例,向下移位6例,居中4例,均为单发病灶,其形态呈圆形、卵圆形、扁平及带状不规则形。游离髓核与同节段供体椎间盘髓核在各序列均类似。MRI诊断与手术病理结果符合率高于CT,比较差异有统计学意义(P<0.05)。结论:MRI诊断腰椎间盘脱出及髓核游离准确率高,值得临床应用。Objective：To evaluate the diagnostic value of MRI for herniated lumbar disc with dissociate of nucleus pulposus.Method：The clinic and MRI data of 20 patients with herniated lumbar disc with dissociate of nucleus pulposus confirmed by surgery in our hospital from July 2014 to October 2015 were retrospectively analyzed.Result：Of all the 20 cases,the nucleus shifted upward in 10 cases,downward in 6 cases and in 4 cases was in the middle.The lesion was single,with round,oval,flattened or ribbon irregular shape.The signals of the dissociate nucleus were similar to those of the disc nucleus pulposus in the same segment.MRI showed a higher diagnose coincident rate with surgical pathologic than CT,the difference was statistically significant（P〈0.05）.Conclusion：MRI shows high diagnosis accuracy for herniated lumbar disc with dissociate of nucleus pulposus,so it is worthy of clinical application.
