 The purpose of this study is to see if magnetic resonance imaging MRI and magnetic resonance spectroscopic imaging MRSI can tell which patients with prostate cancer are at a low risk for their cancer growing and spreading. Magnetic resonance methods use magnets and radio waves to take pictures of body structure MRI and to measure amounts of important chemicals within the body MRSI. This study will look at the structural and chemical properties of prostates before undergoing treatment. Hopefully, doctors will be able to use this method before making treatment decisions for patients with newly diagnosed cancer of the prostate. This study will continue our work to assess the value of MRIMRSI in addressing what is currently one of the greatest clinical challenges in the management of prostate cancer: the identification of low-risk organ-confined prostate cancer that can be managed expectantly with deferred treatment.
