State-of-the-art PET/CT acquisitions allow for the repeated sweeps of extended axial imaging ranges during the emission scan following the injection of the tracer. These data can be reconstructed in contiguous frames (see Frame 1-8 as an example) that are used to extract time-activity curves of tissues and organs. This information, in turn, can be used to derive parametric images (e.g., ki and distribution volume, DV) beyond static images that yield SUV quantification only. It is assumed that parametric image information supports more accurate diagnosis in the future. (Figure made with contributions from Rahmim (2019) and Keio Gijyuku University Hospital, Japan)
