Imaging procedures
For both tracers, whole body PET-acquisition started from the mid-thigh to at least the base of the skull. PET scans were acquired in three-dimensional (3D) mode with an acquisition time of 3 min per bed position or equivalent for continuous acquisition. Overall, PET coverage was identical to the anatomical CT scan range. Low-dose CT acquisition of parameters (such as kV, mAs, pitch in helical CT, dose modulation, etc.) was performed in accordance with institutional protocols.Acquisition procedure for [
