摘　　要：目的:探讨磁共振脊髓水成像在腰椎间盘突出诊断中的价值。方法:采用Siemens Avanto1.5T磁共振扫描仪、常规MR及水成像技术,回顾分析32例腰椎间盘突出患者常规MRI及水成像扫描的MR表现。结果:腰椎间盘突出的脊髓水成像表现为椎管内脑脊液液体柱的腹侧、腹外侧及背侧的弧形压迹呈蜂腰样或糖葫芦状。结论:腰椎磁共振水成像技术可间接显示硬膜囊受压及神经根移位程度,是常规MRI检查的有效补充。Objective To investigate the value of magnetic resonance myelography for the diagnosis of lumbar disc herniation, Methods 32 patients with lumbar disc herniation were analyzed retrospectively who underwent MR imaging by common sequences and myelography in a 1.5-T MR Siemens imagine unit. Results The comma-shaped impression was found in gastro, lateral gastro and dorsal cerebrospinal fluid, which looked like bee-waist or crystalline candied haw.Conclusion Magnetic resonance myelograpby is an effective supplement to common MR method as it indirectly shows the compressed dural sac and displaced nerve roots.[Chinese Medical Equipment Joumal,2010,31 （2）：74-75]
