Our Published Research



We have a multi-disciplinary research team composed of radiologists, urologists, medical oncologists, radiation oncologists, pathologists, medical physicists and molecular biologists working on developing new imaging and image guided technologies for prostate cancer. The two overarching aims of our research are “non-invasive and accurate diagnosis of aggressive prostate cancer using MR imaging“ and “eradication of localized prostate cancer with minimal complications using minimally invasive treatment methods”.  Our group has already has developed new MR sequences, pilot CAD software for prostate MRI and tested MR guided therapy methods such as laser and focused ultrasound ablation in clinical and pre-clinical studies.
