据科学技术厅放射线综合研究所发表,用高分辨力PET(释放阳电子断层摄影装置)确立了纹状体黑质变性症的诊断方法。纹状体黑质变性症是招致手震颤及步行困堆等帕金森氏综合征的疾病。从解剖死亡患者的结果,查明纹状体黑质变性症是由于脑内的神经细胞集团-纹状体损害引起的疾病。而PET是以整个脑为对象的诊断方法。研究是以与多巴胺D_2受体(存在于神经细胞,是神经传递物质多巴胺的受体)特异性结合的放射性药剂(碳11—麦克尔
According to the Radiological Comprehensive Institute of Science and Technology, a diagnostic method for striatal substantia nigra degeneration has been established using high resolution PET (positron emission tomography). Striatum nigral degeneration is a disease that causes hand tremor and Parkinson’s syndrome on foot. From the results of dissecting death patients, it was found that striatal substantia nigra degeneration is a disease caused by damage to the neuron group in the brain, the striatum. PET is a diagnostic method that targets the entire brain. The study is a radiopharmaceutical that binds specifically to the dopamine D 2 receptor, a receptor for dopamine, a neurotransmitter present in nerve cells (carbon 11-michael
