(a) Cardiac cine imaging with cardio-respiratory synchronization in the volunteer. Additional functional information can be obtained by evaluating the movement of myocardial wall along the respiratory motion in a given cardiac phase. (b) Clinical breath-held cardiac cine imaging using a Cartesian trajectory and retrospective ECG-gating in a patient with arrhythmia and corresponding free-breathing cardiac cine imaging with cardio-respiratory synchronization.
