摘　　要：目的：探讨磁共振脂肪抑制技术在老年人腰椎病变中的临床应用研究。方法：2012-05~2013-05对120例年龄60~80岁老年人腰椎退行性改变患者行磁共振检查（MRI）,磁共振检查序列包括快速自旋回波脉冲序列（FSE）T2WI、自旋回波脉冲序列（SE）T1WI、脂肪抑制序列等。回顾性分析腰椎退行性改变的MRI表现。结果：MRI检查在常规SE序列中显示病灶110例（91.6%）,FSE序列中显示病灶116例（96.6%）,脂肪抑制序列中显示病灶120例（100%）,病变在脂肪抑制序列里显示最明显。结论：脂肪抑制技术在老年人腰椎病变中能清楚显示磁共振常规扫描中发现不了的病变,尤其在老年人有相关临床症状时脂肪抑制技术非常必要,为影像科诊断医生出具正确诊断提供技术支持,建议在老年人腰椎磁共振扫描中常规加扫脂肪抑制序列。Objective： To investigate the diagnosis of lumbar vertebral diseases with fat--suppression technology of magnetic resonance in old people. Methods： A total of 120 patients（60-80Y） with degenera- tive lumbar spine were analyzed retrospectively. All patients were examined by MRI including fast spin echo（FSE）T2WI, spin echo（SE）T1WI and fat--suppression sequences. Results： Of all the 120 patients, 110 （91.6%） were discovered by routine MR sequence,ll6 （96.6%） were discovered by FSE, and 120（100%） were discovered by fat suppressed sequence. The best result was obtained by fat suppression technology. Conclusion：The fat--suppression technology show the lesions which are difficult to be found by routine MR sequence. It＇s especially useful in the old people with related symptoms, and should be taken as a routine sequence in the MR examination of lumbar vertebrae.
