High-Resolution Diffusion-Weighted Imaging to Detect Changes in Tumor Size and ADC, and Predict Adverse Biopsy Histology During Prostate Cancer Active Surveillance.

HR-DWI outperforms S-DWI in predicting AH. Patient with AH have tumors that change in size and ADC that could be detected using HR-DWI. Future studies with longer follow-up should assess HR-DWI for predicting disease progression during AS.
