Our purpose was to evaluate the diagnostic accuracy of MRI in moyamoya disease. We studied 30 patients with this disease, comparing MRI and angiographic findings. The diagnostic value of MRI was evaluated for occlusive lesions, collateral vessels, and parenchymal lesions. In all patients bilateral occlusion or stenosis of the supraclinoid internal carotid artery and proximal anterior and middle cerebral arteries was clearly shown by MRI, and staging of the extent of occlusion agreed with angiographic staging in 44 (73%) of 60 arteries. MRI, particularly coronal images, clearly showed basal cerebral moyamoya vessels in 54 hemispheres, and 45 of a total of 71 large leptomeningeal and transdural collateral vessels were identified. MRI also showed parenchymal lesions in 48 (80%) hemispheres, and the extent of occlusion in the anterior and posterior circulations respectively correlated with white matter and cortical and/or subcortical infarcts.
我们的目的是评估磁共振成像（MRI）对烟雾病的诊断准确性。我们研究了30例患有此病的患者，比较了MRI和血管造影的结果。评估了MRI对闭塞性病变、侧支血管和实质病变的诊断价值。在所有患者中，MRI清晰显示了双侧床突上段颈内动脉以及大脑前动脉和大脑中动脉近端的闭塞或狭窄，并且60条动脉中有44条（73%）的闭塞程度分期与血管造影分期一致。MRI，尤其是冠状位图像，在54个半球清晰显示了基底节区烟雾病血管，共识别出71条大的软脑膜和经硬膜侧支血管中的45条。MRI还在48个（80%）半球显示了实质病变，前后循环的闭塞程度分别与白质以及皮质和/或皮质下梗死相关。
