Abstract

Abstract: A 75-year-old woman with Takayasu arteritis was referred to 18 F-FDG PET/CT due to elevated C-reactive protein in her laboratory data. FDG PET/CT with semiconductor detectors revealed no uptake in the arterial walls, suggesting active inflammation. However, the blood pool uptake in the proximal portion of the left subclavian artery was defective, suggesting arterial occlusion. Magnetic resonance angiography revealed complete occlusion of the left subclavian artery. Ultrasonography showed the reverse flow of the left vertebral artery. Semiconductor PET can visualize the blood pool defects of the intra-arterial uptake in the arterial branches from the aorta.

18F-FDG半导体PET/CT检测高松动脉炎动脉闭塞为血池缺损。

摘要：一名75岁女性高须动脉炎患者因实验室数据中c反应蛋白升高而接受18F-FDG PET/CT检查。FDG PET/CT与半导体检测器显示动脉壁未见摄取，提示活动性炎症。然而，左锁骨下动脉近端部分的血池摄取有缺陷，提示动脉闭塞。磁共振血管造影显示左锁骨下动脉完全闭塞。超声显示左椎动脉逆流。半导体PET可以显示动脉分支动脉内摄取的血池缺陷。
