PZ - DWI

No abnormality (i.e. normal) on ADC and high bvalue DWI.

Linear/wedge-shaped hypointense on ADC and/or linear/wedge-shaped hyperintense on high b-balue DWI.

Focal (discrete and different from the background) hypointense on ADC (arrow) and/or focal hyperintense on high b-value DWI; may be markedly hypointense on ADC or markedly hyperintense on high b-value DWI, but not both.

Focal markedly hypointense on ADC (arrow) and markedly hyperintense on high b-value DWI; < 1.5cm on axial images.

Same as 4 but ≥ 1.5cm in greatest dimension (arrow) or definite extraprostatic extension / invasive behavior.
