| 摘 要： | 目的：分析烟雾病（moyamoya disease,MMD）的磁共振成像（magnetic resonance imaging,MRI）及磁共振血管造影（magnetic resonance angiography,MRA）的表现,探讨软脑膜高信号（常春藤征Ivy征）对烟雾病的诊断价值。方法：回顾性分析10例成人MMD患者的MR（包括MRI和MRA）和临床资料,MRI至少包括T1WI、T2WI、FLAIR,MRA采用3D TOF法。结果：处在不同阶段的MMD患者,在MRI上可见大脑前中动脉的异常,双侧基底节区见血管流空信号影I、vy征、梗塞灶和出血;MRA表现为双侧颈内动脉虹吸部末端和（或）邻近双侧大脑前中动脉部分狭窄或闭塞,大脑后动脉增粗延长,moyamoya血管。结论：Ivy征对MMD的诊断有重要价值,认识Ivy征对病情进展有重要的参考意义。
