* indicates statistically significant
Data represent the mean ± SD
Acquisition duration of partial scan reconstruction and average CT was 16 min in 8 phase gated mode respectively. Emission data were acquired utilizing RPM after 90
min interval of FDG injection
Acquisition duration of clinical PET/CT was 2 min/bed. Emission data were acquired after 60 min interval of FDG injection under free shallow breathing with no voice
