 The purpose of this study is to see if dynamic contrast enhanced DCE MRI imaging makes it possible to distinguish benign conditions of the breast from malignant tumors and provide better information than can be obtained with regular MRI. DCE MRI uses a new way of collecting and analyzing the images or pictures which provides doctors extra information not available with standard imaging methods. This includes information about the blood vessels of different breast diseases. Pictures produced this way look just like the regular MRI pictures. The DCE MRI adds another imaging sequence another scan to the MRI examination ordered by your physician to evaluate your breast lesion, thus increasing the exam time extra 10 min. The information gained from doing the new test, the DCE MRI, will not be used in your treatment and will not affect the type of care you receive for your breast lesions.
