 The goal of this and future research is to maximize the effectiveness of prostate imaging in order to minimize the morbidity of prostate biopsy and hence improve the quality of life of patients with prostate cancer. There are many applications to improved imaging of prostate cancer, but several the investigators are interested in include: improved risk stratification to limit unnecessary treatment while providing appropriate treatment to prevent progression; limiting the number of biopsies needed for diagnosis andor decreasing the frequency of biopsies and hence decreasing biopsy-related morbidity; focal therapy for confirmed focal disease rather than treating the entire prostate in order to limit the significant morbidity associated with whole-gland treatment.
