Effective sensitivity of dPET (322 ps) versus cPET (550 ps) as a function of 18F-FDG activities for object diameters of 20, 30, and 40 cm. It indicates a 1.3–5.5× effective sensitivity improvement of dPET with improved quality of counts compared to cPET over the measured activity of 7.4–337 MBq 18F-FDG, although the NEMA sensitivity of dPET is lower than cPET’s
