Overview
Brief Summary
Magnetic Resonance Spectroscopy (MRS) is a novel imaging technique for noninvasive probing of biochemical properties of tissue. While MRS does not generate images of tumor per se it allows biochemical spectroscopic data to be obtained in vivo from user defined region-of-interest. In this manner, biochemical information elucidated by MRS can be interpreted in relation to detailed anatomy and images of metabolite distribution can be created. The aim of MRS is to identify presence and concentration of metabolites characteristic for normal and abnormal (tumor) cellular activities hence allow differential normal tissue from pathological tissue, as well as allow differentiating malignant from benign tumors.
Detailed Description
Recent in vivo studies have reported successful use of 1H and 31P MRS in differentiating between benign and malignant tumors in breast tissue. These studies demonstrated an increase in the choline metabolite peak that reflects an increase in choline-containing metabolites in 70-80% of breast carcinomas, as compared to 14-18% of benign breast tumors.The objectives would be to determine sensitivity/specificity of MRS in the context of breast CA, We will use normal volunteers to test software and to develop and optimize MR scan sequences prior to or during the testing of target subjects with suspicious breast lesion.
