正电子发射计算机断层显像简称 PET(Positron EmissionComputed Tomography),PET 是集核物理、放射化学、分子生物学、医学影像学和计算机等高新技术之大成,能从分子水平上反映人体的生理、病理变化、异常生化、代谢改变,使复杂的生化、生物分子显像、受体显像成为现实,被誉为现代医学高科技之冠。目前全世界 PET 近500台,绝大多数集中在美国(200多台)、欧洲(近100台)和日本(33台)到目前为止我国已引进了十余台 PET(其中有7个 PET 中心),大多分布在北京、上海、广州等大城市,以及部队系统301医院、南方医院、长海医院等。
Positron Emission Computed Tomography (PET) is a synthesis of positron emission computed tomography (PET). PET is a synthesis of high-tech nuclear medicine, radiochemistry, molecular biology, medical imaging and computer science. It can reflect the physiological and pathological Changes, abnormal biochemistry, metabolic changes, the complex biochemical, biomolecular imaging, receptor imaging become a reality, known as the highest of modern medical science and technology crown. At present, there are nearly 500 PET in the world, most of which are concentrated in the United States (more than 200), Europe (nearly 100) and Japan (33). So far China has imported more than 10 PETs (7 of which are PET centers ), Mostly in major cities such as Beijing, Shanghai and Guangzhou, as well as military system 301 Hospital, Nanfang Hospital and Changhai Hospital.
