Background And Purpose: Xerostomia remains a common side effect of radiotherapy (RT) for patients with head and neck (H&N) cancer despite advancements in treatment planning and delivery. Secretory salivary gland cells express the prostate-specific membrane antigen (PSMA), and show significant uptake on PET scans using Ga/F-PSMA-ligands. We aimed to objectively quantify the dose-response of salivary glands to RT using PSMA PET.

The goal of this study was to assess effects of furosemide and choice of tracer on urinary activity in the bladder and ureters, as well as on occurrence of peri-bladder artefacts in PET/CT.
Methods: Four cohorts with a total of 202 men staged with PSMA PET/CT for prostate cancer received either Ga-PSMA-11 as tracer, with (cohort G+) or without 10mg intravenous furosemide (G-) concurrent with tracer, or F-DCFPyL with (F+) or without furosemide (F-).
Purpose: To test if the relative change in FDG-PET SUV over the course of treatment was associated with disease progression and overall survival. Additionally, the prognostic values of other first-order PET-metric changes were investigated.
Methods: The study included 38 patients with stage II-III NSCLC, who underwent concurrent chemoradiotherapy.
Objective: The purpose of this study was to prospectively investigate the value of a standardized 18F-fluorodeoxyglucose (18F-FDG)-PET/computed tomography (CT) protocol for imaging of primary bladder cancer, using standardized bladder flushing and filling.
Methods: We included 19 patients with cT1-4 bladder cancer. A Foley catheter was inserted before 18F-FDG injection.
