| 目的 探讨MR FLAIR序列成像中常春藤征对成人烟雾病的诊断价值。 方法 回顾性分析21例烟雾病患者的MR FLAIR图像,对常春藤征的分布及程度进行评分并统计。 结果 烟雾病患者MR FLAIR图像显示28侧(66.67%)大脑半球可见常春藤征,表现为沿柔脑膜点状或线状高信号,主要分布在额叶和顶叶,其表现程度与病程有关。 结论 常春藤征在烟雾病的诊断具有重要的价值,认识常春藤征有利于患者病情进展的追踪及治疗后疗效复查。 |

| Objective To observe the diagnostic value of ivy sign on MRI with fluid-attenuated inversion recovery (FLAIR) in adult with Moyamoya disease. Methods MRI of 21 patients with Moyamoya disease was retrospectively reviewed. Ivy sign was referred as leptomeningeal high intensity on FLAIR sequence. According to the distribution and the signal intensity, the score was collected. Results In patients with Moyamoya disease, ivy sign was demonstrated in 28 (66.67%) hemispheres, mostly located in the frontal and parietal lobes. The scores of the ivy sign were related with the progression of Moyamoya disease. Conclusion Ivy sign is valuable in the diagnosis of Moyamoya disease. It is propitious to the following up and evaluation of the theraputic effect. |
