Improving cardiac cine MRI on 3T using 2D k-t accelerated auto-calibrating parallel imaging

Recently, 3D cine has gained attention due to its capability for single breath-hold volumetric measurement 1. Nonetheless, conventional 2D cine maintains two intrinsic advantages, namely, its superior blood-myocardium contrast owing to blood in-flow effects and reduced SSFP banding artifacts with more localized slice-by-slice shimming. These advantages are more prominent at high field. This work intends to optimize a k-t acceleration method, kat ARC 2, for 2D cine and preliminarily investigate its performance vs. 3D cine at 3T.
