title: MR physics in practice: how to optimize acquisition quality and time for cardiac MR imaging.
abstract: The quality of the medical imaging is a key component for accurate disease diagnosis. Optimizing image quality while maintaining scan time efficiency and patient comfort is important for routine clinical MRIs. In this article, we review both practical and advanced techniques for achieving high image quality, especially focusing on optimizing the trade-offs between the image quality (such as signal-to-noise and spatial resolution) and acquisition time. We provide practical examples for optimizing the image quality and scan time.
