Motion-Corrected Real-Time Cine Magnetic Resonance Imaging of the Heart

Rahsepar Fig 4b croppedObjective: Free-breathing real-time (RT) imaging can be used in patients with difficulty in breath-holding; however, RT cine imaging typically experiences poor image quality compared with segmented cine imaging because of low resolution. Here, we validate a novel unsupervised motion-corrected (MOCO) reconstruction technique for free-breathing RT cardiac images, called MOCO-RT. Motioncorrected RT uses elastic image registration to generate a single heartbeat of high-quality data from a free-breathing RT acquisition.  View/Download
