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.
