Synopsis

Keywords: Cardiovascular, Image Reconstruction

Highly-accelerated real-time cine MRI is a rapid technique that is particularly useful for patients with arrhythmia, dyspnea, and/or pediatric patients who may not be able to follow breath-hold instructions. Incorporating view-sharing (VS) and k-space weighted image contrast (KWIC) filtering into a compressed sensing (CS) reconstruction framework improves spatio-temporal resolution in our 32-fold accelerated real-time free-breathing cine MRI using radial k-space sampling. Resulting biventricular volumetric parameters are relatively accurate, which may eliminate the need for sedation/anesthesia in pediatric patients.
