摘　　要：目的:评价CT对腰椎间盘突出症的诊断价值。材料与方法:回顾分析500例腰椎间盘突出症的临床表现和CT所见。结果:腰椎间盘突出好发于L4/L5、L5/S1两个节段,其主要CT征象:①突入椎管内的髓核所形成的软组织块影;②硬脊膜囊受压、变形、移位;③神经根肿胀、受压移位或湮没;④碎块形成、滑移;⑤Schmorl结节形成;⑥突出的髓核部分钙化;结论:CT是诊断腰椎间盘突出症的重要方法,其准确率在91%以上,且能清楚显示局部伴随征象。但也有一定的误诊。Purpose： To evaluate the value of CT diagnosis in lumbar disk herniation. Materials and Methods： The clinical finding and CT view of 500 cases with lumbar disc herniation were retrospectively analyzed. Results： Herniation occured frequently at the level of L4 - S1 intervertebral space. The main CT featttres of the herniated intervertebral disc were as follows： ①soft tissue mass formed by extrusion of the disc into the spinal canal; ②compression, distortion and displace ment of the dural sac; ③swelling, compressing displacement and obliteration of nerve root; ④formation and migration of disc fragment; ⑤formation of Schmorl＇ s nodule; ⑥partial calcification of herniated nucleus pulposus; Conclusion： CT is an important method in the diagnosis of lumbar disc herniation and its accuracy is 91%. But there still exists misdiagnosis.
