摘　　要：目的:正电子发射计算机断层扫描是核医学发展的一项新技术,阐述PET成像原理、发展动态、存在的问题以及发展趋势。方法:从PET的定义开始,介绍原理,临床应用,优缺点和发展动态。结果:PET在心、脑、肿瘤等器官的功能、血流和代谢情况的分析和早期诊断方面具有广泛的应用前景。结论:PET的发展推动了影像医学和临床医学的整体发展,PET/MRI和PET/CT复合系统的应用将核医学影像引向一个新的领域,必将对人类的健康发挥重要的作用。Objective： The Positron Emission Tomography is the new technology in development of the Nuclear Medicine. The aim of this study was to explore the image- forming principle, development trends, the existence question and the outlook of PET. Methods： The definition of PET was firstly explained. Then, we introduced not only the imaging theory and clinical applications, but also the advantage and the disadvantage of PET. Results： PET is more widely used in analysis and early diagnosis of the heart and brain and tumor＇s function, blood stream and metabolism. Conclusion： The development of PET impels the whole progress in imaging medicine and clinical medicine. The application of the complex system of PET/MRI and PET/CT will bring the Nuclear Medicine image to the new level. It＇s undoubted that the PET will play an important role in the human＇s health.
