The present study investigates the clinical utility of cardiac cine-MRI using free-breathing scan with serial motion averaging (SMART) and Compressed-SENSE (C-SENSE). Left ventricular functional parameters derived from free-breathing SMART with C-SENSE showed good correlations to those from conventional breath-hold technique. Cine-MRI with C-SENSE can reduce both scan time (around 40% of the scan time) and burden of multiple breath-holdings without any penalty for the image quality; therefore, it might contribute to great advantages in routine clinical work.
