功能影像是利用放射性核素或核素标记物作示踪剂,通过机体细胞对其摄取和代谢反映机体生化过程,或是利用功能成像软件反映机体功能变化的成像方法。它主要包括正电子发射断层(positron em ission tomography,PET)、单光子发射计算机断层扫描(single photon em ission computed
Functional imaging is the use of radionuclide or radionuclide markers as a tracer, through the body cells uptake and metabolism reflect the body’s biochemical processes, or the use of functional imaging software to reflect changes in body function imaging method. It mainly includes positron em ission tomography (PET), single photon em ission computed (single photon em ission computed)
