Abstract
A 73yearold gentleman underwent radical prostatectomy due to prostate cancer 2003 during his followup he presented with biochemical recurrence prostatespecific antigen 2 ng/ml 1 Positron emission tomography PET/CT with 11Ccholine was performed 5 min after injection of 706 MBq of 11Ccholine The images revealed a moderate uptake of the left prostate bed which had no morphologic correlate in the diagnostic CT The configuration of the uptake and its moderate intensity maximum standardized uptake value 27 made the lesion hard to be differentiated from any other unspecific finding Hence he underwent simultaneous wholebody PET/MRI Siemens Biograph mMR acquisition immediately after PET/CT In the dynamic MRI an early contrastenhanced lesion was found in the region of the moderate uptake seen in PET/CT This additional finding increased the level of suspicion of malignancy
