18F-FDG PET image biomarkers improve prediction of late radiation-induced xerostomia

Current prediction of radiation-induced xerostomia 12months after radiotherapy (Xer12m) is based on mean parotid gland dose and baseline xerostomia (Xerbaseline) scores. The hypothesis of this study was that prediction of Xer12m is improved with patient-specific characteristics extracted from 18F-FDG PET images, quantified in PET image biomarkers (PET-IBMs).
