2019-05-31 杨中华 脑血管病及重症文献导读

示例一,颅内动脉粥样硬化。 示例二,原发性中枢神经系统血管炎。

示例一,颅内动脉粥样硬化。 a 图,颅内 DSA 显示右侧 MCA M1段局部狭窄(白色箭头)。b 图,高分辨血管壁 平扫MRI显示右侧 MCA M1段局灶性偏心增厚(白色箭头)。c 图,相应部位 T2序列显示血管壁高信号(箭头)。d 图,增强 T1序列显示局灶性偏心血管壁强化。e 图,T2序列高分辨放大图显示右侧 MCA M1段游离高信号,周围低信号(白色箭头):





示例二,原发性中枢神经系统血管炎。a 图,DSA 显示右侧 ICA 海绵窦段明显狭窄。b 图,平扫 T1显示双侧ICA 岩骨-海绵窦段血管壁弥漫性环形增厚(白色箭头),左侧明显。c 图,增强 T2序列显示双侧血管壁呈等-高信号(箭头)。d 图,增强 T1序列显示双侧岩骨-海绵窦 ICA 血管壁环形强化(白色箭头):

血管壁MR越来越多地用于颅内动脉瘤患者,动脉瘤壁强化(aneurysmal wall enhancement,AWE)被认为与动脉瘤不稳定或破裂有关。3D TSE是最常使用的血管壁MR序列,包括黑血效应;然而血流也会引起管腔强化。
