To test the hypothesis that both coronary anatomy and ventricular function can be assessed simultaneously using a single four‐dimensional (4D) acquisition.

A free‐running 4D whole‐heart self‐navigated acquisition incorporating a golden angle radial trajectory was implemented and tested in vivo in nine healthy adult human subjects. Coronary magnetic resonance angiography (MRA) datasets with retrospective selection of acquisition window width and position were extracted and quantitatively compared with baseline self‐navigated electrocardiography (ECG) ‐triggered coronary MRA. From the 4D datasets, the left‐ventricular end‐systolic, end‐diastolic volumes (ESV & EDV) and ejection fraction (EF) were computed and compared with values obtained from conventional 2D cine images.

The 4D datasets enabled dynamic assessment of the whole heart with isotropic spatial …
