Total-Body PET/Computed Tomography Highlights in Clinical Practice: Experiences from Zhongshan Hospital, Fudan University.

Abstract

The initial experience of using total-body PET/computed tomography (CT) (uExplorer) in Zhongshan Hospital, Fudan University, is described. Compared with conventional PET/CT, total-body PET/CT imaging provides more comprehensive information for evaluation of disease. Using fludeoxyglucose F 18, regular-dose (3.7 MBq/kg), low-dose (1.85 MBq/kg), or extra low-dose (0.37 MBq/kg) scanning, as well as high-quality imaging, protocols were used in clinical practice according to the situation. Dynamic studies were also used to assess tumor biological characteristics or for radiotracer angiography.
