目的  探讨磁共振扩散加权成像(DWI)、动脉自旋标记技术(ASL)、磁共振血管成像(MRA)联合应用在缺血性脑血管病诊断中的价值。 方法  对2010年3月-2012年5月经临床和影像学诊断的104例缺血性脑血管病患者,行常规MRI、液体衰减反转恢复序列、DWI及ASL、MRA序列检查,分析DWI、ASL、MRA多种技术显示病变的信号特征、面积大小及与血管关系。 结果  DWI对急性及亚急性脑梗死的检出率为100%,对大、小面积梗死病灶检出率无明显差异;ASL对大、小面积的急性及亚急性脑梗死的检出率有差异,对大面积梗死检出率为100%,对小面积梗死的检出率为70%;DWI和ASL对短暂性脑缺血发作的检出率分别为0%、70%,液体衰减反转恢复序列对短暂性脑缺血发作患者大脑皮层下斑状缺血灶检出最敏感。 结论  DWI和ASL均可用于急性脑梗死的早期诊断,ASL对大、小面积的急性及亚急性脑梗死的检出率有差异,DWI、ASL及MRA联合应用可准确评估缺血半暗区及侧支血管情况,在缺血性脑血管病诊断中有重要价值。
