mpMRI of a 72-year-old male with a serum PSA of 6.9 ng/mL. Axial (A), sagittal (B), coronal T2WI (C), high b-value DWI (D), ADC map (E), and DCE MRI (F). Patient has a focal lesion in right mid peripheral zone which is hypointense on axial (A) and coronal (C) T2WIs, and has a focal contrast uptake on DCE (F). However, due to large amount of rectal gas, visible on axial and sagittal T2WIs (asterisk), high b-value and ADC map images are distorted and lesion cannot be visualized (arrowheads). Targeted biopsy of the lesion revealed a Gleason grade 7 (3+4) prostate adenocarcinoma.
