^agm T₂: geometric mean T₂

^bLWF: luminal water fraction

^cPZ: peripheral zone

^dTZ: transition zone.

^*Malignant PZ significantly different than non-malignant PZ (P<0.05) based on paired t-test. Paired t-test could not be conducted in TZ due to the insufficient number of patients with tumors in TZ.
