Normal values for 18F-FDG uptake in organs and tissues measured by dynamic whole body multiparametric FDG PET in 126 patients
Autor: André H. Dias, Allan K. Hansen, Ole L. Munk, Lars C. Gormsen
Publikováno v: EJNMMI Research, Vol 12, Iss 1, Pp 1-14 (2022)
Abstract Background Dynamic whole-body (D-WB) FDG PET/CT is a recently developed technique that allows direct reconstruction of multiparametric images of metabolic rate of FDG uptake (MRFDG) and “free” FDG (DVFDG). Multiparametric images have a m
