摘　　要：Objective: to analyze the characteristics of magnetic resonance imaging (MRI) and magnetic resonance angiography (MRA) in moyamoya disease. Methods: clinical and imaging data of 70 patients with moyamoya disease admitted to our hospital from March 2018 to March 2020 were randomly selected. Results: MRI and MRA examination of 70 patients with moyamoya disease showed thinning of bilateral internal carotid artery, middle cerebral artery and anterior cerebral artery and poor blood flow. Smoke flow signal appeared on both sides of the middle line of skull base, and showed the best axial T2WI. FLAIR showed pointy or striped "Ivy signs" of hyperintensity in the pia meninges on both sides of the cerebral hemispheres, with more frontal and parietal lobes. 26 patients with T2WI and FLAIR also showed corolla radiography, and the white matter semiooval center showed brush-like hyperintensity brushes perpendicular to the lateral ventricular wall. 30 patients showed empty basal ganglia signal on T2WI. After MRI diagnosis, 35 cases of cerebral infarction, 9 cases of anterior hemorrhage. Conclusion: MRA and MRI can show the characteristic signs of collateral circulation in patients with moyamoya disease, as well as the adverse results caused by vascular stenosis and stroke, which are worthy of promotion and application in clinical treatment.
