目的：回顾性研究极外侧型椎间盘突出症的特征性MRI 影像表现及对临床诊治的价值。方法收集2013年1月-2014年12月我院241例经手术证实的椎间盘突出病例，其中包含63例极外侧型椎间盘突出患者，共73处病变，根据其1.5TMRI表现进行回顾性研究，分析其影像诊断特征、伴发病变、好发位置与分型比例关系，判断MRI对极外侧型椎间盘突出的鉴别价值。结果极外侧型椎间盘突出发生于L4-5、L5-S1节段的比例为71.1%，椎间孔亚型的好发比例为56.2%，伴发骨质退变、椎间盘变性的比例高达98.4%， MRI鉴别诊断极外侧型椎间盘突出的敏感性为75.3%，特异性为98.1%，准确性为92.2%，阳性预测值为93.2%，阴性预测值为92%。结论 MRI 是一种无创伤性的能准确诊断极外侧型椎间盘突出的成像方法，对临床的诊治工作具有重要的指导作用。
目的：迴顧性研究極外側型椎間盤突齣癥的特徵性MRI 影像錶現及對臨床診治的價值。方法收集2013年1月-2014年12月我院241例經手術證實的椎間盤突齣病例，其中包含63例極外側型椎間盤突齣患者，共73處病變，根據其1.5TMRI錶現進行迴顧性研究，分析其影像診斷特徵、伴髮病變、好髮位置與分型比例關繫，判斷MRI對極外側型椎間盤突齣的鑒彆價值。結果極外側型椎間盤突齣髮生于L4-5、L5-S1節段的比例為71.1%，椎間孔亞型的好髮比例為56.2%，伴髮骨質退變、椎間盤變性的比例高達98.4%， MRI鑒彆診斷極外側型椎間盤突齣的敏感性為75.3%，特異性為98.1%，準確性為92.2%，暘性預測值為93.2%，陰性預測值為92%。結論 MRI 是一種無創傷性的能準確診斷極外側型椎間盤突齣的成像方法，對臨床的診治工作具有重要的指導作用。

Objective To evaluate the clinical diagnostic value of the 1.5TMRI imaging characteristics of the far lateral lumbar disc herniation (FLLDH)by respective study. Methods To collect 241 cases confirmed to be protrusion of intervertebral disc by surgical operation at Luhe hospital from Jan.2013 to Dec.2014.Among these patients,63 cases are the diagnosis to be FLLDH with totally 73 lesions. According to the 1.5TMRI imaging findings of these patients, the imaging characteristics, concomitant lesions, predilection site and the relationship of typing and ratio are analyzed, thereby estimating the diagnosis value of MRI in FLLDH.Results In 73 lesions of 63 patients diagnosed to be FLLDH, 52 lesions (71.1%) are founded at L4-5 segment and L5-S1 of the spin, 41 lesions (56.2%) are the intervertebral foramen subtype. And, 68 lesions (93.2%) occurred with concomitant bone degeneration, intervertebral disc degeneration. The sensitivity of the MRI diagnostic method in FLLDH is 75.3%, the specificity is 98.1%, the accuracy is 92.2%,the negative predictive value is 93.2%,and the positive predictive value is 92%.Conclusion MRI is a noninvasive imaging method, and can accurately diagnose the far lateral lumbar disc herniation. To analyze the imaging features of FLLDH is significant for guiding clinical diagnosis and treatment.
