Consensus ratings for arterial vessel and pathology delineation, vessel-tissue contrast, artifacts and overall image quality.

For qualitative analysis images were evaluated, utilizing a five-point scale: 5 = excellent, 4 = good, 3 = moderate, 2 = poor, and 1 = non-diagnostic. AVM: arteriovenous malformation AVF: dural arteriovenous fistula. Consensus ratings for arterial vessel and pathology delineation, vessel-tissue contrast, artifacts and overall image quality.为开展定性分析，本研究采用五分制评分量表对图像进行评估，评分标准为：5分=优秀，4分=良好，3分=一般，2分=较差，1分=无法诊断。 动静脉畸形（arteriovenous malformation, AVM）；硬脑膜动静脉瘘（dural arteriovenous fistula, AVF）。 针对动脉血管与病变勾画、血管-组织对比度、伪影情况及整体图像质量开展共识评分。
