目的：探讨ＭＲＩ及ＭＲＡ对小儿脑动脉炎的诊断价值。材料和方法：回顾分析１１例小儿脑动脉炎ＭＲＩ及ＭＲＡ表现。结果：小儿脑动脉炎ＭＲＩ主要表现为多发性脑梗死，脑出血与脑梗死同时并存等。ＭＲＡ主要表现为脑动脉狭窄、管腔粗细不均，管壁变硬等。依据脑动脉病变部位可将小儿脑动脉炎分作主干型和末梢型。结论：ＭＲＩ与ＭＲＡ相结合可对小儿脑动脉炎做出比较准确的诊断。
Objective: To investigate the diagnostic value of MRI and MRA in children with cerebral arteritis. Materials and Methods: The MRI and MRA manifestations of 11 children with cerebral arteritis were retrospectively analyzed. Results: The main manifestations of MRI in children with cerebral arteritis were multiple cerebral infarction, coexistence of cerebral hemorrhage and cerebral infarction. MRA mainly manifested as cerebral artery stenosis, uneven lumen, wall hardening and so on. According to the site of cerebral artery lesions in children with cerebral arteritis can be divided into the main trunk and distal type. Conclusion: The combination of MRI and MRA can make a relatively accurate diagnosis of cerebral arteritis in children.
