Figure 2a:

Images in a 71-year-old patient with a history of previous negative transrectal US-guided biopsy and a serum PSA level of 16.09 ng/mL. (a) Axial T2-weighted MR image shows an area of low signal intensity in the right anterior transition zone (arrows). (b) Axial apparent diffusion coefficient (ADC) map obtained with DW MR imaging shows a hypointense lesion in this same location (arrows). (c) DW (b = 2000 sec/mm² ) MR image shows this lesion (arrows) as a hyperintense focus. (d) Whole-mount pathologic specimen obtained at robotic-assisted prostatectomy shows Gleason 4+4 disease (red outline) in the same location. MP MR imaging correctly depicted the tumor and enabled us to estimate the tumor burden in this patient.
