Figure 7:

Images in a 72-year-old man with a serum prostate-specific antigen level of 8.95 ng/mL. (A) Axial T2-weighted MRI scan shows a focal hypointense lesion in the left apical–mid anterior peripheral zone (arrow). (B) Apparent diffusion coefficient map and (C) diffusion-weighted image with a b value of 1500 sec/mm2 show the lesion with mild to moderate diffusion restriction (arrows). (D) Biparametric MRI–based artificial intelligence model’s binary prediction map overlaid on the T2-weighted MRI scan automatically segments the prostate gland (blue shading) and detects the same lesion that was shown in other sequences (arrow; red shading). Transrectal US/MRI fusion–guided biopsy revealed Gleason 3+4 prostate cancer within this lesion.
