|Dynamic PET Perfusion Imaging (DPPI) to Characterize Thoracic Tumors: A Phase I Assessment of Ultra-fast Digital PET as an Imaging Biomarker|
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.
