Example images from a subject with arrhythmia and prolonged breath-hold acquired using both the gold-standard breath-hold and ECG-gated cine (first and third rows) and the real-time non-gated and free-breathing imaging technique (second and fourth rows) for three different slice locations in both end-diastole and end-systole; note the significant artifacts in the gold-standard images (as noted by the reviewers) and the comparatively sharp endocardial border definition in the real-time images. The EF was found to be 33.9% and 35.2% for the standard and real-time measurements, respectively. The real-time images were rated better in every category than the gold-standard images by the reviewers; all but one of the ratings for the real-time images were “excellent”, whereas more than half of the gold-standard ratings were “good” and the rest “excellent”.
