Table 2 General patient characteristics and main PET parameters recorded or computed in the different groups imaged in clinical routine with the Vereos (digital-PET) or Ingenuity (analog-PET) camera and after the injection of 3 MBq.kg-1 of current 18F-labeled tracers, with an additional patient imaged after the injection of 7 MBq.kg-1 of 82Rb on the Vereos camera. Continuous variables are presented with median values [minimum – maximum values after exclusion of outliers]

From: Fully digital PET is unaffected by any deterioration in TOF resolution and TOF image quality in the wide range of routine PET count rates
