The use of gated CMR can be limited by motion artifacts secondary to cardiac and respiratory motion. Imaging is especially challenging in patients with arrhythmias or those who cannot perform adequate breath-holds. Real-time CMR is a non-gated technique that has been successfully applied in scenarios where standard segmented acquisitions break down. In this study, we sought to accelerate real-time acquisition by using sparse sampling with an iterative SENSE reconstruction.
Highly accelerated real-time CMR using sparse sampling with iterative SENSE reconstruction can be successfully applied in patients and volunteers with accurate calculation of LV functional parameters. Image quality is reduced relative to gold-standard segmented acquisitions, but is superior to standard real-time acquisitions. 1. Liu J, et al. ISMRM 20th Annual Meeting.
