摘　　要：目的研究并比较CT与MRI对于诊断极外侧型腰椎间盘突出的准确性。方法从2011年1月到2013年3月,选取我院被诊断为极外侧型腰椎间盘突的病患共82例,作为研究对象。以数字法随机分成观察组(41例)和对照组(41例)。观察组病患通过MRI确定极外侧型腰椎间盘突出的阳性检出率;对照组病患通过CT确定极外侧型腰椎间盘突出的阳性检出率。对比两组极外侧型腰椎间盘突出的阳性检出率。结果观察组I度检出率为36.59%(15/41),阳性检出率为97.56%(40/41),均显著高于对照组的21.95%(9/41),75.61%(31/41)。差异均有统计学意义(均P<0.05)。观察组漏诊率为2.44%(1/41)显著少于对照组的24.39%(10/41)。差异均有统计学意义(均P<0.05)。结论 MRI对极外侧型腰椎间盘突出的检出率显著,并且MRI可明显减低漏诊率,具有积极意义,值得临床推荐。Objective To study and compare the accuracy of CT and MILl in the diagnosis of extreme lateral lumbar disc herniation. Methods 82 cases of patients diagnosed with extreme lateral lumbar disc herniation in our hospital from January 2011 to March 2013 were selected as the research objects, they were divided into observation group （41 cases） and control group （41 cases） by random number table method. The observation group got positive detection rate of extreme lateral lumbar disc herniation by MILl, the control group got that by CT. Compared the positive detection rate of two groups, Results The I detection rate of observation group was 36.59%（15/41）, positive detection rate was 97.56%（40/41）,which were significantly higher than that of control group[21.95%（9/41）, 75.61%（31/41）],with statistical significance（p〈0.05）. The rate of misdiagnosis in observation group[2.44%（1/41）] was significantly lower than control group[24.39%（10/41）], the differences had statistical significance（p〈0.05）. Conclusion Detection rate of extreme lateral lumbar disc herniation by MRI is significant, and MRI can decrease the rate of nfisdiagnosis significantly, which deserves to be recommended in clinic.
