A 61-year-old patient (Pat ID #13) with biopsy-proven prostate cancer undergoing [68Ga]Ga-PSMA-11 PET/CT for initial tumor staging before treatment. Gleason Score was 9, PSA was 18.3 ng/ml at the time of imaging. a–c show images acquired with the reference acquisition protocol; d–f show images acquired with the reduced acquisition protocol all reconstructed with OSEM-PSF + TOF(4i). Maximum intensity projection (a, d) and axial [68Ga]Ga-PSMA-11 PET/CT slices (b, c, e, f) show local tumor (red arrows). One right pelvic lymph node metastasis (black arrow) could not be unequivocally detected with a three and a half-fold scan time reduction (c, f). Until now the patient has not undergone surgery, a follow-up scan performed more than 6 months later confirmed the prostatic and lymph node lesions
