title: Coronary MR angiography revealed: how to optimize image quality.
abstract: Magnetic resonance (MR) imaging of the coronary arteries has been challenging, owing to the small size of the vessels and the complex motion caused by cardiac contraction and respiration. Free-breathing, whole-heart coronary MR angiography has emerged as a method that can provide visualization of the entire coronary arterial tree within a single 3-dimensional acquisition. Although coronary MR angiography is noninvasive and without radiation exposure, acquisition of high-quality coronary images is operator dependent and is generally more difficult than computed tomographic angiography. This article explains how to optimize acquisition of coronary MR angiography for reliable assessment of coronary artery disease.
