Figure 2.
Multiparametric magnetic resonance images obtained at 3 T in a 75-year-old man with a prostate-specific antigen level of 31 ng/mL and history of two prior negative systematic biopsies. T2-weighted imaging (A) showed an ill-defined lenticular area with marked low-signal intensity in the anterior third of both transition zones (arrows). This area showed a marked restriction of diffusion on the apparent diffusion coefficient map (B, arrows), and almost no enhancement at dynamic contrast-enhanced imaging (C, arrows). Targeted biopsies showed a Gleason score 7 (4 + 3, 60% of grade 4) cancer with a maximum cancer core length of 15 mm.
