The overall goal of this proposed pilot study is to validate, based on tissue-based measures, quantitative measures of tissue function obtained non-invasively by dynamic contrast enhanced (DCE) MRI, diffusion-weighted (DW) MRI, and proton MR spectroscopy (1H MRS) techniques for assessing the effects of pre-surgical chemotherapy in breast cancer patients who are eligible to receive preoperative chemotherapy.
The specific aims of this project are: (1) to incorporate DCE-MRI, DW-MRI, and MRS techniques and analysis tools into the clinical MRI exam to determine longitudinal changes in permeability, cellularity and metabolism in breast tumors of breast cancer patients undergoing pre-surgical chemotherapy; and (2) to compare quantitative MR measurements from patients with histopathological and immunohistochemical (IHC) findings from mastectomy and segmental mastectomy specimens. |
