A 65-years old patient (Pat. ID #7) with second biochemical recurrence after primary prostatectomy and salvage external beam radiation therapy. PSA was 0.6 ng/ml at the time of imaging. ac show images acquired with the reference acquisition protocol; df show images acquired with the reduced acquisition protocol, all reconstructed with OSEM-PSF + TOF(4i). Pathological tracer uptake in a mediastinal lymph node visible on the images acquired with reference protocol (c, black arrow) was not reproducible with three and a half-fold reduction in scan time duration (f). Maximum intensity projection (a, d) and axial [68Ga]Ga-PSMA-11 PET/CT slices (b, c, e, f) show pelvic and extrapelvic lymph node metastases (black arrows) and bone metastases (red arrows)
