The images of a 67-year-old patient with prostate-specific antigen of 5.46 ng/ml. a Transverse T2-weighted images on MRI showed a lesion in the right peripheral zone (red arrow). b DWI with b1500 shows a moderately high signal on the edge of right peripheral zone (red arrow). c ADC map showed a moderate hypo intensity on the edge of right peripheral zone (red arrow). All the finding results in a PI-RADS 3. d, e PET showed great intense focal uptake on the right peripheral zone (red arrow), which is equal to the parotid gland, resulting in an MI-ES 3. Readers rated the images from mpMRI as negative for extraprostatic extension (Likert scale points = 2), whereas they rated the images from.68 Ga-PSMA-11 PET/CT and mpMRI + PET/CT as positive for extraprostatic extension (Likert scale points = 4 and 6). f Whole mount histology confirms the tumor in the right peripheral zone without extraprostatic extension (red arrow)
