Abstract:Background: Virtual contrast-enhanced (vCE) imaging techniques are an emerging topic of research in breast MRI. Purpose: To investigate how different combinations of T1-weighted (T1w), T2-weighted (T2w), and diffusion-weighted imaging (DWI) impact the performance of vCE breast MRI. Materials and Methods: The IRB-approved, retrospective study included 1064 multiparametric breast MRI scans (age:52 ±12 years) obtained from 2017-2020 (single site, two 3T MRI). Eleven independent neural networks were trained to der… Show more
