Abstract

A 5-dimensional imaging method and system is provided to acquire and display the effect of dynamic physiologic changes (either spontaneous or induced) on cardiac function of a patient's heart to elucidate their effects on diastolic myocardial function. In a patient free-breathing magnetic resonance imaging study, 3-dimensional spatial information is encoded by a non-Cartesian 3-dimensional k-space readout trajectory and acquired concurrently with recordings of cardiac and respiratory cycles. The advantage of using non-Cartesian sampling in this invention compared to, for example, Cartesian sampling is higher scan acceleration, improved robustness to motion/flow effects (incoherent instead of coherent artifacts) and robustness to missing data points in k-space.
