Figure 3

The PSA level at the time of imaging was 21.0 ng/mL. A regression in lesion size after pelvic irradiation confirmed the malignant nature of the lesions. A. Axial PET/CT fusion image showing focal 11C-choline uptake in the area of the right external iliac vessels (white arrow, SUV max 3.6). The lesion shows focal signal elevation on both the 500 ms b-image using DWI B. (black arrow) and the STIR image C. (white arrow). D. Axial fusion T1w image showing enlarged lymph nodes (20 mm) close to the right external iliac vein.
