Dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) is an important tool for the diagnosis of breast cancer. It is of great importance to develop new MRI acquisition and analysis methods that can yield improved biomarkers with higher specificity for the diagnosis of breast lesions. The purpose of the present study is to explore visualization and quantitative information of tumor-associated vessels to improve diagnostic accuracy of breast tumors (MR BI-RADS 4). The results show that combination of quantitative breast vascular information may provide an accurate means for the diagnosis of breast cancer.
