High-resolution magnetic resonance (MR) image has been introduced to diagnose and follow-up moyamoya disease and visualized moyamoya vessels and internal carotid artery stenosis. This study was performed to assess the utility of MR angiography (MRA) for the evaluation of anastomotic channels through the external carotid artery (ECA) in moyamoya disease patients.
Twenty patients with moyamoya disease were reviewed. The cortical anastomosis and superficial temporal artery (STA), middle meningeal artery, and deep temporal artery by MRA were evaluated and were compared with those by digital subtraction angiography if obtained. Fifteen patients (24 hemispheres) underwent bypass surgery, including encephaloduroarteriosynangiosis in 14 hemispheres and STA-middle cerebral artery anastomosis with encephalomyosinangiosis in 10 hemispheres. Five patients did not undergo any surgery.
MRA could show these vessels and the patency of anastomosis formed by the surgery and also showed naturally formed anastomosis and ECA tributaries in the patients who did not undergo any surgery.
MRA provides useful information for follow-up evaluation on the development of the ECA system in moyamoya disease.
高分辨率磁共振（MR）成像已被用于诊断和随访烟雾病，并可视化烟雾血管和颈内动脉狭窄。本研究旨在评估磁共振血管造影（MRA）在评估烟雾病患者通过颈外动脉（ECA）的吻合通道方面的效用。
回顾了20例烟雾病患者。通过MRA评估皮质吻合以及颞浅动脉（STA）、脑膜中动脉和颞深动脉，并与数字减影血管造影（如有）进行比较。15例患者（24个半球）接受了搭桥手术，包括14个半球的脑硬脑膜动脉血管融合术和10个半球的STA-大脑中动脉吻合术及脑肌血管融合术。5例患者未接受任何手术。
MRA可以显示这些血管以及手术形成的吻合口的通畅情况，还可以显示未接受任何手术的患者中自然形成的吻合口和ECA分支。
MRA为烟雾病患者ECA系统发育的随访评估提供了有用信息。
