For radiologists, mass-like DCIS on breast MRI is unable to be distinguished from invasive ductal cancer by bare eyes. However, different treatment strategies for these two entities pushed us to do the differentiation using innovative approaches. By combining usage of tumor dynamic curve type on DCE, whole tumor shape features and features from GLCM to reflecting heterogeneity inside certain areas on MR images, we were able to achieve diagnostic accuracy 84.7% in telling DCIS from IDC in mass-like lesions, by using only one feature from each categories.
