磁共振灌注及弥散成像在早期脑梗塞诊断的价值

磁共振弥散加权成像和血流灌注成像不仅可以超早期诊断脑梗塞，明确缺血部位，范围，估计缺血半暗带的大小和鉴别短暂性脑缺血发作；特殊磁共振序列还可以确诊早期颅出血，有助于溶栓对象的筛选和预后的判断。为溶栓治疗提供直观的影像学依据。

Applications of MR Perfusion and Diffusion Imaging in the Early Cerebral Infarction

MR Perfusion weighted imaging and diffusion weighted imaging are useful in the hyperacute cerebral is chemia,and may be a potentially useful adjunction tool in the prediction of the outcome of ischemia cerebrovascular disease and also helpful in the diagnosis and differentiation of cerebral disease.
