For deep invasion, the AUC was 0.649 for T2WI, 0.906 for T2WI + DWI, and 0.906 for T2WI + DCE-MRI (Tables 4 , 5 ) The chi-square test revealed a highly significant association between the MRI findings and the histopathological stage for T2WI (χ2 = 28.666, p = 0.001), T2WI + DWI (χ2 = 66.696, p = 0.0005), and T2WI + DCE-MRI (χ2 = 78.186, p = 0.0005) (Tables 6 - 8 ).
