MRI of the prostate gland showing diffuse prostatitis. T2 weighted (a), high b value 1500 DWI (b), ADC map (c) and dynamic contrast-enhanced (d) images show the prostate gland with a volume of 30 cc with a Foley catheter in situ (arrowhead). The peripheral zone is diffusely mildly T2 hypointense (a) (arrow). There is diffuse restricted diffusion (b, c), which is greater in the transition zone with lower signal intensity on the ADC map (c) (arrow). There is diffuse mild (d) hypervascularity (arrow)
