The reliability of the left-ventricular ejection function estimated from the compress-sensing accelerated cardiac MR scan was evaluated in the study. Excellent inter-observer and intra-observer agreement were observed based on the data from the compress-sensing cardiac MR scans, suggesting the usefulness of compress-sensing acceleration in improving the patient comfort and scan time reduction without degrading the reliability in the cardiac output assessment.
