Using low temporal resolution Cine CMR has a significant drawback in assessing the heart function, since the details of myocardial deformation go undetected. In this study we introduce the retrospective triggering acquisition scheme in combination with compressed sensing reconstruction to obtain very high frame Cine CMR in an acquisition time shorter than the time needed for a gold standard reconstruction. High acceleration factors were achieved without significant losses in image quality and derived cardiac functional parameters.
