Research objective:The calcification (size < 1 mm) in the prostate close to the bladder could be clearly observed using [18F]NaF radiolabelled molecule. The identification of the mouse prostate is a challenging task using in vivo imaging due to its size and shape. Images were made using the IRIS PET system (Inviscan). The system demonstrates high sensitivity and excellent spatial resolution.
