摘　　要：目的:探讨双回波稳态进动磁共振序列在极外侧型腰椎间盘突出症的显示情况及在临床诊治中的应用价值。方法:回顾性分析9例极外侧型腰椎间盘突出症患者的腰椎MRI常规序列和双回波稳态进动序列的图像,评价双回波稳态进动序列在极外侧型腰椎间盘突出症患者临床诊治中的应用价值。结果:由于腰椎MRI矢状位对极外侧型腰椎间盘突出症的诊断不敏感,造成9例极外侧型腰椎间盘突出症患者影像诊断上的误诊和漏诊;而双回波稳态进动序列在这9例患者的图像中明确显示L4～5腰椎间盘突出5例,L5S1腰椎间盘突出4例;其中左侧突出7例,右侧突出2例。结论:双回波稳态进动磁共振序列在极外侧型腰椎间盘突出症中的扫描图像,可以清晰显示突出椎间盘与腰骶部脊神经根的卡压情况,提高了对于该型腰椎间盘突出症诊断的准确性,为临床医师在术中的定位起到极大的帮助。TO explore the display of DESS magnetic resonance sequence in FLLDH（far lateral lumbar disc herniation） and its value in the clinical diagnosis and treatment. Methods： Retrospective analysis of 9 cases of far lateral lumbar disc herniation in patients with lumbar MRI conventional sequence and DESS（ double-echo steady-state precession） sequence of images, evaluate the application value of DESS sequence in clinical diagnosis and treatment of far lateral lumbar disc herniation. Results ：The lumbar MRI sagittal insensitive to the diagnosis of extreme lateral lumbar disc herniation resulted in misdiagnosis and missed diagnosis in 9 cases of far lateral lumbar disc herniation ; DESS sequence in the 9 patients images clearly show L4-5 lumbar intervertebral disc herniation in 5 patients,and L5S1 lumbar protrusion in the other 4 cases;herniation on the left side in 7 patients,herniation on the left side in 2 cases. Conclusion：The herniated lumbosacral nerve root entrapment can be clearly showed by DESS magnetic resonance scan image sequence in the far lateral lumbar disc herniation,it can improved accuracy for the diagnosis of lumbar disc herniation and play a great help for clinical physician in the intraoperative localization.
