We proposed to use a variational network (VN) reconstruction algorithm with a 1-dimensional convolutional neural network (CNN) as a temporal regularizer for DCE-MRI reconstruction in this study. We used our newly developed breast perfusion simulation pipeline, to generate simulate data and train the reconstruction model. The machine learning (ML) reconstruction shows non-inferior structural similarity and improved visual image quality when compared with the iGRASP reconstruction. The ML reconstruction also takes much less time than the iGRASP reconstruction.
