摘　　要：正电子发射计算机断层成像技术(PET)是一种基于功能改变的显像技术,能够通过特定的示踪剂在体内的分布特点来反映体内某方面的功能代谢水平。近年来,PET诊断得到了越来越多的临床认可,其显像系统也发展迅速,多种功能PET仪器相继推出,2017年国内推出了全球首台全景动态扫描PET/CT(轴向视场为196.6 cm)。本文将对近年来PET/CT的技术发展和全景动态扫描PET/CT研究突破进行相关综述。Positron emission computed tomography （PET） is a molecular functional-level imaging technique that can reflect the functional metabolism of an aspect of the body through the development of a specific tracer injected in the body. In recent years, the application values of PET diagnosis has been more and more clinically recognized, and the imaging system has also developed rapidly, like a variety of functional PET instruments have been developed and introduced. In 2017, the world＇s first panoramic dynamic scan PET/CT （axial vision Field is 196.6 cm） launched at home. Therefore, this paper will review the technical developments of PET/CT in recent years and the breakthroughs of dynamic scanning PET/CT.
