摘要
目的 探讨和评估磁共振断层血管造影 (MRTA)在面肌抽搐病人中的诊断价值 ,并比较多平面和单一横断位MRTA的作用。方法 本组包括 12 1例面肌抽搐病人和 30例正常对照者 ,均作了磁共振断层血管造影。结果 多平面MRTA诊断的敏感性为 94.39% ,特异性为 88.8% ,优于单一横断位 ,与单一横断位MR TA相比 ,两者具有显著性差异 (P <0 .0 5 )。正常对照组单一横断位和多平面MRTA诊断的准确率分别为 6 5 .0 %和 96 .7% ,两者具有相当显著的统计学差异 (P <0 .0 1)。结论 多平面MRTA在面肌抽搐病人的检测和评估中具有相当的价值。
Objective To evaluate the magnetic resonance tomographic angiography (MRTA) in diagnosis of hemifacial spasm and compare the efficacy of multiplane and axial source MRTA. Methods Magnetic resonance tomographic angiography (MRTA) was performed in all 121 patients with hemifacial spasm and 30 controls without as. Results The sensitivity of the multiplane MRTA was 94.3% with a specificity of 88.8%. The difference between the axial source and multiplane was statistically significant ( P <0.05). The diagnostic accuracy of the control group was 65.0% and 96.7% in the axial source and multiplane, respectively. The difference was obviously significant ( P <0.01). Conclusion MRTA examination is considered to be a useful diagnostic modality for the evaluation of patients with hemifacial spasm and being helpful in preoperative management.(Shanghai Med J, 2000,23∶741-743)
