Abstract

The present invention relates to a method of performing dynamic contrast enhanced magnetic resonance imaging of an object (10) with signal separation for water and fat, the method comprising acquiring magnetic resonance datasets in the k-space using Dixon acquisition in a chemical shift encoding space and dynamic time resolution in a dynamic time space, wherein the dataset acquisition is performed employing undersampling, wherein the method further comprises: applying a compressed sensing reconstruction technique in the k-space, the chemical shift encoding space and the dynamic time space, said compressed sensing reconstruction resulting in reconstructed datasets, —performing Dixon reconstruction on the reconstructed datasets and dynamic contrast analysis on the Dixon reconstructed datasets.
