摘要 目的:讨论于急性脑梗死患者的治疗中,液体衰减反转恢复成像(FLAIR)与磁共振弥散加权成像(DWI)对发病时间预测及溶栓治疗指导的应用价值。方法:选取2014年3月至2015年2月间于我院治疗且已知发病时间的急性脑缺血患者共54例,对其行MR FLAIR及DWI成像,分析发病时间与其阳性结果间的关联,同时确定一切点,若于切点内的大多数患者发病时间均≥6h,则对该部分患者进行溶栓治疗。结果:54例患者DWI序列于6h内有88.90%显示为阳性,6h后所有患者均显示为阳性;于发病6h内,有11.1%患者FLAIR序列显示为阳性,6h后FLAIR序列为阳性患者数量逐渐增加到100%。结论:在无法确定患者发病时间时,DWI序列显示为阳性且FLAIR序列显示为阴性的患者,大多发病时间≤6h(溶栓时间窗内),应对该部分患者及时行溶栓治疗。
