超声心动图（GE）成像被认为是检测脑淀粉样血管病（CAA）出血性变化的一种手段。然而，几乎25%的CAA患者在T2* GE成像上没有显示微血管。我们应用了一种新的成像方法，磁敏感加权成像（SWI），以评估微血管的存在。在CAA的疑似病例中，认知效应也存在，我们表明SWI在检测微血管方面比传统方法敏感得多。
Gradient-echo (GE) imaging is recognized as a means to detect hemorrhagic changes in cerebral amyloid angiopathy (CAA). However, almost 25% of patients with CAA do not show microhemorrhages on T2* GE imaging. We applied a new imaging method, susceptibility weighted imaging (SWI), to evaluate the presence of microhemorrhages. In a suspected case of CAA, where cognitive effects are also present, we show that SWI is much more sensitive in detecting microhemorrhages than conventional methods.
