一名 48 岁男性患有复发性眩晕,抗血小板药物治疗无效。脑血管造影显示双侧椎动脉闭塞,侧支循环不良。使用 15 O 2 气体的 PET 显示双侧小脑半球的血流量和氧代谢率降低,氧提取分数升高。随后的 18 F-FRP170(1-(2-18 F-氟-1-[羟甲基]乙氧基)甲基-2-硝基咪唑)PET 描绘了缺氧但存活的组织,显示相同区域的示踪剂摄取升高。颞浅动脉-大脑后动脉吻合术后,15 O-gas PET 显示双侧小脑半球血流、氧代谢率和氧提取分数正常化。这些区域中 18 F-FRP-170 摄取异常升高的问题也得到解决。
A 48-year-old man experienced recurrent vertigo refractory to antiplatelet medications. Cerebral angiography showed occlusion of bilateral vertebral arteries with poor collateral circulation. PET using 15 O 2 gas showed reduced blood flow and metabolic rate of oxygen and elevated oxygen extraction fraction in bilateral cerebellar hemispheres. Subsequent 18 F-FRP170 (1-(2-18 F-fluoro-1-[hydroxymethyl] ethoxy) methyl-2-nitroimidazole) PET, which depicts hypoxic but viable tissue, revealed elevated tracer uptake in the same regions. After superficial temporal artery-posterior cerebral artery anastomosis, 15 O-gas PET showed normalization of blood flow, metabolic rate of oxygen, and oxygen extraction fraction in bilateral cerebellar hemispheres. Abnormally elevated 18 F-FRP-170 uptake was also resolved in those regions.
