Figure 1.
A 62-year-old man with serum PSA of 3.15 ng/mL. (A) Axial T2W MRI, (B) ADC map of DW image, and (C) ktrans map derived from DCE MRI demonstrate a 1cm right apical mid-peripheral zone lesion (arrow). (D, E) MR spectroscopy was diagnostic and negative with a choline/citrate ratio of 0.243 +/− 14% (arrow). (F) Subsequent transrectal ultrasonography/MRI fusion-guided biopsy revealed Gleason 3+4 cancer in the lesion (up to 55% core involvement).
