弥散加权ＭＲＩ(ＤＷＩ)可检测超早期急性缺血高信号组织中水的表观弥散系数 (ＡＤＣ)的降低 ,现已广泛应用于实验性卒中和卒中病人的研究。作者将 8只ＳＤ雄性大鼠 ( 3 10～ 3 3 0 ｇ)右侧大脑中动脉短暂闭塞 (ＭＣＡＯ) 3 0分钟 ,在闭塞期 (即将再灌注前 )及再灌注后即刻、3
Diffusion-weighted MRI (DWI) can detect the decrease of apparent diffusion coefficient (ADC) of water in ultra-early acute ischemic hyperintense tissue and has been widely used in the study of patients with experimental stroke and stroke. The authors transiently occlude the right middle cerebral artery (MCAO) for 8 SD male rats (3 10-3 300 g) for 30 minutes before occlusion (immediately prior to reperfusion) and immediately after reperfusion
