| 目的 比较脑葡萄糖代谢显像、脑血流灌注显像及磁共振灌注成像三种检查方法在诊断缺血性脑血管病中的价值。方法 对78 例缺血性脑血管病患者和26 例单侧脑血管病变患者的脑葡萄糖代谢显像、脑血流灌注显像及磁共振灌注成像进行对比分析。结果 所有患者用脑葡萄糖代谢显像、脑血流灌注显像及磁共振灌注成像三种检查方法检出的阳性率分别为97. 44 %、94. 87 %和82. 05 % ,脑葡萄糖代谢显像、脑血流灌注显像与灌注加权磁共振成像结果比较均有显著性差异( P 值分别为0. 012 、0. 002) 。26 例单侧血管病变患者用三种检查方法检出的阳性率分别为96. 15 %、92. 31 %、92. 31 % ,三者无显著性差异( P = 0. 552) 。结论 脑葡萄糖代谢显像、脑血流灌注显像对诊断缺血性脑血管病较敏感,在诊断单侧血管病变中三种检查方法均较敏感。 |

| Objective To compare the diagnostic value of cerebral glucose metabolism imaging , cerebral blood flow perfu-sion imaging , and MR perfusion weighted imaging ( PWI) in patient s with ischemic cerebrovascular diseases. Methods Wecompared the result s of 78 patient s with ischemic cerebrovascular diseases and 26 patient s with only single-side involvementwhounderwent all the three examinations. Results The positive rates of brain glucose metabolism imaging , cerebral bloodflow perfusion imaging and PWI in 78 patient s were 97. 44 % , 94. 87 % and 82. 05 % , respectively. Compared brain glucosemetabolism imaging , brain blood flow perfusion imaging with PWI , there were significant differences ( P = 0. 012 and 0. 002 ,respectively) . The positive rate of brain glucose metabolism imaging , cerebral blood flow perfusion imaging and PWI in 26patient s with single2side involvement were 96. 15 % , 92. 31 % and 92. 31 % , respectively , and there was no significant differ-ence among them (P = 0. 552) . Conclusion Brain glucose metabolism imaging and cerebral blood flow perfusion imagingwere sensitive in diagnosing ischemic cerebrovascular diseases. But the three methods were all sensitive in diagnosing ische-mic cerebrovascular diseases caused by single-side affected vessels. |
