Ga-PSMA-11 PET/MRI: determining ideal acquisition times to reduce noise and increase image quality.

Background: In this study, we investigate the impact of increased PET acquisition time per bed position on lesion detectability, standard uptake value, and image noise in Ga-PSMA-11 PET/MRI scans.

Methods: Scans of twenty patients were analyzed in this study. Patients were injected with Ga-PSMA-11 (mean, 5.
