Figure.1 56-year-old man with prostate-specific antigen level of 5.6 ng/mL. Arrows present Prostate Imaging Reporting and Data and System (PI-RADS) category 4 lesions visible in the peripheral zone.A , Axial T2-weighted MR image shows lesion in the left-mid peripheral zone. The dimension of the lesion is 1.0 cm which is consistent with the PI-RADS score of 3 on T2-weighted image. B ,C, show that the lesion is hypointense on DWI(b=50 s/mm2) and hyperintense, on DWI(b=1800 s/mm2). D , Apparent Diffusion Coefficient map, indicates that the lesion is mildly hypointense, making it PI-RADS score of 3 on DWI. E (precontrast T1-Weighted) and F,Dynamic contrast enhancement MR image shows early enhancement within same location as lesion in A–D with early enhancement for overall PI-RADSv2.1 score of 4. TRUS-guided cognitive MRI fusion biopsy is detected prostate cancer with ISUP 1.
