Methods and materials

 

Dynamic FDG PET/CT was performed prior to radiation therapy of advanced thoracic tumors (lung and esophageal) in 24 patients using a next-generation digital photon counting system (Vereos Philips, dPET).

 

DPPI was performed at the time of bolus injection of ~185 MBq FDG over a volume of interest for 15 min.

 

PET listmode data were reconstructed using a range of 1 sec/fr to 60 sec/fr.

 

Blinded review by two experienced PET readers and descriptive statistics were calculated for data analysis.
