Vasculitis is defined as inflammation and necrosis with leukocytic infiltration of the blood vessel wall. Takayasu arteritis is a chronic inflammatory arteritis that primarily involves the aorta and its main branches. A 64-year-old female patient with a 2-month history of fever of unknown origin was presented to our clinic for F-18 FDG PET/CT imaging. Baseline PET/CT images demonstrated intense F-18 FDG uptake in the aorta, bilateral subclavian and brachiocephalic arteries consistent with Takayasu arteritis. After 2 months of immunosuppressive therapy, she was asymptomatic and follow-up FDG PET/CT scan showed almost complete disappearance of large vessels' F-18 FDG uptake. FDG PET/CT is a sensitive technique for assessing presence of large-vessel vasculitis such as Takayasu arteritis, extent of large-vessel inflammation and disease activity after therapy.

血管炎定义为血管壁炎症、坏死伴白细胞浸润。高安动脉炎是一种主要累及主动脉及其主要分支的慢性炎症性动脉炎。一名64岁女性患者，有2个月不明原因发热病史，到我院进行F-18 FDG PET/CT成像检查。基线PET/CT图像显示主动脉、双侧锁骨下动脉和头臂动脉有强烈的F-18 FDG摄取，符合高安动脉炎表现。经过2个月免疫抑制治疗后，她无症状，随访FDG PET/CT扫描显示大血管F-18 FDG摄取几乎完全消失。FDG PET/CT是评估高安动脉炎等大血管血管炎的存在、大血管炎症范围及治疗后疾病活动度的敏感技术。
