Keywords: Low-Field MRI, Low-Field MRIA standard cine MRI exam typically collects a stack of short-axis slices to cover all left ventricular myocardium and uses electrocardiogram gating and breath-holds. Real-time imaging methods are often used to resolve issues with insufficient gating signal or breath-hold failure. In this work, we demonstrate that real-time SMS cardiac imaging at 0.55T provides sufficient blood-myocardium contrast and regional wall motion evaluation with three-fold acceleration compared to real-time single-band and Cartesian breath-hold ECG-gated cine. We also show an alternative reconstruction approach, clustered locally low rank that can improve image quality.
