Free-running 5D whole-heart imaging (5D CMR) has been proposed as a means of simplifying CMR exams by capturing the entire 3D cardiac anatomy without the need for ECG gating or breath-holds. We demonstrated that 5D CMR with ferumoxytol enhancement enables the evaluation of cardiac function in comparison to ECG gated 2D CINE images in congenital heart disease patients. In addition, it enables evaluation of the cardiac morphology with improved diagnostic quality in ~40% of the cases. This suggests that the free-running approach has the potential for replacing the conventional 2D imaging for evaluation of both cardiac function and morphology.
