Conventional Ultrasound for Imaging of Prostate Cancer Extent and Response in Human Cancer Patients

In this observational study the investigators will undertake imaging studies on men with prostate cancer. The primary hypothesis is that ultrasound spectroscopy could be used to determine the extent of disease inside and outside of the prostate gland in patients with prostate cancer. It is hoped that the changes in ultrasound backscatter parameters obtained before radical prostatectomy could be used to correlate with pathological findings from the prostate specimen after surgery.
