Multi-parametric MR imaging of transition zone prostate cancer: Imaging features, detection and staging

Figure 4 Left TZ tumor of prostate gland demonstrated by MR. A: Axial T2W image depicts ill defined, round, homogenous hypointense tumor (arrows); B: DWI depicts focal area of bright signal on left mid gland (arrow); C: K-trans map in dynamic contrast-enhanced MR imaging (DCE-MRI) clearly localizes the tumor and reveals some internal heterogeneity.
