 The purpose of the study is to test a new approach to see if the test results can be reproduced each time the Magnetic resonance imaging MRI is done for an individual patient. The study will explore the use of an imaging agent called hyperpolarized 1-13C pyruvate HP with MRI scans. MRI is a technique that takes pictures of the bodys organs using a magnetic field and radiofrequency waves that cannot be felt. In order to accomplish the goal of the study the patient will have two hyperpolarized MRI scans to assess if scans can be reproduced. The hyperpolarized MRI scans will be compared with the pathological results of the surgery to see if the hyperpolarized MRI provides additional information regarding disease metabolism.
