Synopsis

Keywords: Breast, CancerThe present study aimed to evaluate the feasibility of 3D quantitative synthetic MRI for discriminating the immunohistochemical (IHC) status of invasive ductal carcinoma (IDC) of the breast. We found that volumetric T1 and T2 values of IDC varied according to IHC status, including those for hormone receptors and Ki-67, indicating the feasibility of this method for discriminating the IHC status of IDC of the breast.
