Volume: 53 cc
Exam quality: Moderate.
Peripheral zone: In addition to focal lesion below, there are band-like areas of T2 hypointense without associated significant associated restricted diffusion compatible with sequela of prostatitis/fibrosis.
Transition zone: There are a few encapsulated and/or circumscribed BPH nodules as well as T2 hypointensity between nodules

DWI: Marked diffusion restriction. (ADC: 859, Focal markedly hypointense on ADC and markedly hyperintense on high b-value DWI; <1.5cm in greatest dimension) (DWI score 4),
DCE: Positive.
Overall category: PIRADS 4- High (clinically significant cancer is likely to be present).
