早期弥散加权成像及血管成像在临床急性脑梗死溶栓治疗的应用

The Application of Brain DWI and MRA in the Clinical Treatment of Thrombolysis in Acute Cerebral Infarction.

目的 研究早期弥散加权成像（DWI）对急性脑梗死溶栓治疗的指导及临床意义。方法 回顾性调查急性脑梗死30例，对30例患者的影像学资料进行分析，结合临床表现及溶栓效果和病因分析判定早期DWI和MRA对临床的指导作用。结果 早期DWI结合MRA可以判定梗死缺血区对应的血管分支，指导溶栓选择，其中静脉溶栓28例，动脉溶栓2例，3例为多发性梗死，颈内动脉狭窄2例。结论 DWI可显示早期脑梗死病灶，早期头颅MRI结合磁共振血管成像（MRA）检查可指导临床溶栓选择。

Objective To study the guidance and clinical significance of brain DWI and MRA for the treatment ofthrombolysls in acute cerebral infarction Methods Retrospective analysis was undertaken in 30 cases with acute cerebral infarction so as to explore the importance of early DWI and MRA check for the treatment of thrombolysis in acute cerebral infarction. Results The DWI together with MRA can assess the cerebrovascular branch concerned about the infarction area and suggest the better way of thrombolysis between the alternatives arterious and intravenous thrombolysis. Conclusion The DWI check call display the lesion of the cerebral infarction while the early Brain DWI and MRA check can recommend the selection between arterious and intravenous thrombolysis in cerebral infarction.
