The PhD candidates will develop advanced 4D flow MRI in the heart and large vessels. The project is funded by the Dutch Technology Foundation STW. In this project we aim to develop and validate a novel 4D flow MRI strategy, which includes image acquisition, reconstruction, as well as analysis methods. This will allow flow imaging at unprecedented spatiotemporal resolution within clinically accepted scan time. The developed methodology will eventually provide new insights in severity and progression of congenital heart diseases. Experts in both MRI (A.J. Nederveen, G.J.
