新的磁共振成像（ＭＲＩ）技术可以诊断早期脑梗死部位和范围。弥散加权磁共振成像（ＤＷＩ）可检测早期脑缺血损伤改变，而灌注加权磁共振成像（ＰＷＩ）可检测脑血流的改变，两者结合可以评价脑组织局部缺血和不可逆损害的程度和类型。作者对１７例发病１２ｈ以内的大脑...
New magnetic resonance imaging (MRI) technology can diagnose early stage and extent of cerebral infarction. Diffusion-weighted magnetic resonance imaging (DWI) can detect changes of early ischemic injury, perfusion-weighted magnetic resonance imaging (PWI) can detect changes in cerebral blood flow, the combination of the two can evaluate the degree of brain ischemia and irreversible damage and Types of. The author of 17 cases of onset within 12h of the brain ...
