Body Imaging with Spectroscopy: Breast Studies
Magnetic Resonance Spectroscopy for Breast Cancer Diagnosis and Treatment Response
Breast cancer is a very common disease, affecting 1 in 8 American women in their lifetimes and causing more than 40,000 deaths each year. Magnetic resonance imaging (MRI) has become the premier imaging method for breast cancer, and is now widely used for diagnosis, staging, assessing treatment response, and screening high-risk patients. Magnetic resonance spectroscopy (MRS) is an additional technique that can be used to improve the accuracy of a breast MRI study. After imaging a breast with conventional MRI methods, a chemical “spectrum” can be measured in a suspicious region, providing additional information about the chemical content of that region. This information has been shown to be helpful in distinguishing benign from malignant masses, and can be used to determine if a mass is responding to chemotherapy treatments faster than MRI alone.
The University of Minnesota’s Center for Magnetic Resonance Research has been instrumental in the development of breast MRS. Lead by Michael Garwood and Patrick Bolan, the CMRR breast team has developed key methodologies that have lead the standardization of breast MRS, including novel acquisition techniques , RF coil designs for high-field scanning  artifact suppression methods , and techniques for accurately quantifying the chemical concentrations in breast cancers . Using these techniques, they have performed clinical studies demonstrating how breast MRS can improve diagnostic accuracy  and monitor treatment response . These methods have since been incorporated into an NCI-sponsored multisite clinical trial to determine if the methods can be translated into clinical practice.
