Non-ECG triggered self-navigated radial 3D multiphase whole heart imaging with isotropic spatial resolution for coronary imaging has successfully been implemented and tested in three volunteers for the first time. Respiratory self-navigation without the need for ECG triggering improves ease-of-use while the acquisition time is well defined and independent on respiratory patterns and heart rate. Moreover, the isotropic spatial resolution together with the multiphase acquisition enables multi planar reformatting in any user selected plane and orientation while the cine frame with the best depiction of a given coronary segment can freely be selected.
