Restaging FCH-PET/CT in a 68 y.o. patient with biochemical relapse following radical prostatectomy. Initially, PCa Gleason sum was 7. PSA was 0.35 mg/L at time of examination. Whole-body MIP (a) and transaxial fusion slices (b, c) showed two foci of moderate uptake in the right iliac nodal area (red arrows) that were initially perceived as suspicious for nodal relapse. However, dynamic PET MIP (d) and fusion series (e) showed no early focal activity at either site, which was consistent with urinary activity on the whole-body scan. This study was interpreted as negative and the patient underwent salvage radiotherapy
