摘要
目的:探讨DWI信号强度改变是否可以用来鉴别TIA和卒中。方法:对47例根据临床表现诊断为TIA的患者于发病24小时内及7～14天后行常规MRI扫描及DWI扫描,观察DWI的演变规律。结果:47例根据临床诊断诊断为TIA的患者中有19例DWI上有局灶性高信号(40.43%),经复查不消失,因而应诊断为卒中。结论:DWI的高灵敏度有助于TIA及卒中的鉴别。
Objective：To explore whether changes in DWI signal intensity can be used to identify TIA and Stroke.Methods：Within 24 hours of onset of illness and 7 to 14 days,Observe the evolution of the law of TIA patients with DWI.Results：In the 47 cases diagnosed according to clinical diagnosis of TIA patients,there are 19 cases of focal high signal intensity on DWI（40.43%）,which has been inspected and does not disappear.We believe that this part of the patient should be diagnosed as having stroke.Conclusion：DWI can contribute to the identification of TIA and stroke.
