From: 68Ga-PSMA-11 PET/MRI: determining ideal acquisition times to reduce noise and increase image quality

Graph illustrating how noise (SD/SUVmean) changed as acquisition time per bed position increased for all twenty patients. As acquisition time increased, average noise levels (represented by the black line) decreased from 0.72 ± 0.22 for 0.5 min to 0.31 ± 0.12 for 10 min and were nearly equivalent between 7 and 10 min of acquisition time
