Three patients with neurological disorders (cerebral infarction, progressive multifocal leukoencephalopathy, and multiple sclerosis) underwent F-THK5351 and C-L-deprenyl PET on the same day to visualize lesions undergoing astrogliosis by measuring MAO-B activity. BPND map and SUV image with F-THK5351 as well as Ki map, Ki/K1 map and SUV image with C-L-deprenyl were created. F-THK5351 BPND maps and SUV images clearly identified the lesions undergoing astrogliosis. C-L-deprenyl Ki/K1 maps were close to F-THK5351 images, but very noisy. Ki maps and SUV images were likely affected by the effect of blood flow. Hence, F-THK5351 is superior to C-L-deprenyl for visualizing lesions undergoing astrogliosis.
三位患有神经紊乱疾病(脑梗死、进行性多灶性白质脑病和多发性硬化症)的患者在同一天接受了 F-THK5351 和 C-L-deprenyl PET 检查,以通过测量 MAO-B 活性来观察星形胶质细胞增生的病变。创建了 F-THK5351 的 BPND 图和 SUV 图像以及 C-L- deprenyl 的 Ki 图、Ki/K1 图和 SUV 图像。F-THK5351 BPND 图和 SUV 图像清楚地识别了星形胶质细胞增生的病变。C-L-deprenyl Ki/K1 图与 F-THK5351 图像接近,但非常嘈杂。Ki 图和 SUV 图像可能受到血流效应的影响。因此,F-THK5351 比 C-L-deprenyl 更适合观察星形胶质细胞增生的病变。
