背景：通过磁共振血管成像(MRA)定量检测和评估大动脉炎(TA)的疾病活动性。方法：将26例大动脉炎患者分为活动组和非活动组。所有患者均行延迟增强MRI检查。受累血管分为A型(主动脉及其弓的主要分支)和B型(二级或三级分支)。结果：活动期患者左锁骨下动脉狭窄程度明显高于非活动期患者(14/16，87.5%vs.2/10，20%；P
Background: To measure and assess the disease activity of Takayasu arteritis (TA) quantitatively by magnetic resonance angiography (MRA).Methods: Twenty-six Chinese TA patients were divided into an active group and an inactive group. All patients underwent delayed contrast-enhanced MRI. The vessels involved were categorized into type A (main branches of aorta and its arch) and type B (secondary or tertiary branches). Three quantitative scores were defined to gauge lumen stenosis, vessel wall thickness, and vessel wall enhancement, and compared between groups and types.Results: The patients in the active group had more stenosis in left subclavian artery than those in the inactive group (14/16, 87.5% vs. 2/10, 20%; p
