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。
Objective： To analyze the apearance of magnetic resonance imaging（MRI） and magnetic resonance angiography（MRA） in moyamoya disease, to approach the diagnosis value of leptomeningeal high signal intensities in moyamoya disease. Methods： The MR （including MRI and MR/k） and clinical data of 10 cases of adult MMD patients was retrospectively reviewed. MRI at least including T1WI, T2WI, FLAIR, MRA using 3D TOF method. Results： The patients at different stages of the MMD, on MRI, the anterior cerebral artery （ACA） and middle cerebral artery （MCA） couldn＇ t be seen, moyamoya vessels in the bilateral basal ganglia, leptomeningeal high signal intensities, infarction and hemorrhage could be displayed. On MRA, stenosis or blocking of the distal internal carotid artery, anterior and middle cerebral artery were revealed; thicking and extending of posterior cerebral artery（PCA） was showed; Moyamoya vessles could be displayed. Conclusion： Ivy sign has great value in the diagnosis of MMI）, and has important reference value for the disease progression.
