Abbreviated and ultrafast breast MRI are emerging techniques that are now entering clinical practice and reflect an increasing understanding of breast cancer heterogeneity. These techniques may represent potential answers to shortcomings of mammographic screening, providing an opportunity to curb interval cancers, maximize diagnostic accuracy, and minimize overdiagnosis. Targeting more aggressive tumor subtypes may play a role in evidence-based de-escalation of breast cancer management, and abbreviated techniques have proved promising in early noninferiority studies. Functional characterization of tumors at MRI also has the potential for noninvasive tumor subtyping based on radiomics and radiogenomics and may ultimately streamline increasingly individualized breast cancer care.
