In this study, we analyzed the relationship between CAIPIRINHA-Dixon-TWIST-VIBE (CDTV)-derived DCE parameters and clinicopathological factors, including molecular subtypes of invasive ductal carcinoma (IDC). Our results showed that the values of semi-quantitative parameters were similar for various prognostic factors and molecular subtypes of IDC. However, the values of quantitative inline pharmacokinetic kinetic parameters, kep_minimum and kep_difference, were significantly different for the luminal A and HER2-positive subtypes. AUC value for accurately distinguishing luminal A and HER2-positive subtypes based on combined kep_minimum and kep_difference values was 0.820. Therefore, our study demonstrates that CDTV-derived quantitative parameters are associated with molecular subtypes of IDC.
