Accurate assessment of cardiac size and function plays an important role in diagnosis and management of various heart diseases. For patients with impaired breath-hold capacity or arrhythmias, real time cine imaging may be more useful. Recently, highly accelerated real time cine imaging using a combination of compressed sensing and parallel imaging has been proposed with eight-fold acceleration. While this technique is promising for clinical applications, it has not been validated. The purpose of this study was to validate the relative accuracy of accelerated real time cine MRI for quantitative assessment of ventricular volumes and function in healthy human volunteers.
