In this study, we discriminated the calcium oxalate and calcium phosphate in breast disease. A cup shaped gel phantom containing two types kidney stones was employed to simulate calcification in the breast. The phase values of five phase images with different echo times were measured, those were obtained by a 3D m-FFE sequence to shorten examination time. We conclude that the calcium oxalate and phosphate are distinguishable with the slope of linear approximation of calcifications on high-pass filtered phase images. We believe that this method is useful for the discrimination between benign and malignant breast disease.
