4D flow imaging can provide comprehensive hemodynamical analysis of blood flow through the heart and great vessels; however, acquiring 4D flow images with whole-heart coverage is prohibitively time-consuming. In this work we describe a highly accelerated and fully self-gated whole-heart 4D flow acquisition and reconstruction methodology. Additionally, we show proof-of-concept of a fully self-gated 5-minute whole-heart 4D flow exam and demonstrate good agreement in aortic flow quantification compared to conventional 2D phase contrast.
