Fig. 2.
A RSI overlaid on T2WI and B conventional ADC map in a 64-year-old male with a prostate-specific antigen level of 25.3 ng/mL demonstrates biopsy proven Gleason 4 + 5 involving the right base peripheral zone (white arrow) with right-sided extraprostatic extension (white arrowhead) and osseous metastatic disease to the right anterior acetabular column (black arrow). The ADC map demonstrates marked distortion in the anteroposterior direction, making detection of extraprostatic disease difficult, and demonstrates relatively poor conspicuity of the right acetabular metastasis.
