In Breast MRI, Dixon fat-water separation techniques have been invaluable for the measurement of breast-density in studies of breast cancer risk. A fundamental source of error in Dixon methods arises from differences in the signal intensity from water and fat, associated with differences in proton density and relaxation times. We propose an automated method to introduce a scaling factor that minimizes these errors. We demonstrate our method in a group of 14 subjects, imaged at 3T with different levels of T1-weighting.
