根据病理学观察，严重的脑淀粉样血管病往往伴有多发性点状出血，我们前瞻性地获得了15例老年患者的CT脑叶出血梯度回波MRI。15例中有9例表现出局限于皮质或皮质下区域的伴随瘀点。在10名老年对照患者中，梯度回波MRI上没有出现类似的病变。这些发现表明，脑淀粉样血管病可能是神经放射学诊断和分期在生活中。
Based on the pathologic observation that severe cerebral amyloid angiopathy is often accompanied by multiple petechial hemorrhages, we prospectively obtained gradient-echo MRI on 15 elderly patients with lobar hemorrhage on CT. Nine of the 15 demonstrated accompanying petechial hemorrhages restricted to the cortical or corticosubcortical regions. No similar lesions were present on gradient-echo MRI in 10 elderly control patients. These findings suggest that cerebral amyloid angiopathy might be neuroradiologically diagnosed and staged during life.
