Potential advantages of high field cardiac magnetic resonance imaging include superior signal-to-noise ratio, image contrast and spectral separation. These might be used to improve spatial and/or temporal resolution and imaging speed. However, high field imaging presents new challenges to the operator, including increased magnetic field heterogeneity, susceptibility, artefacts and higher specific absorption rate. Recently, studies have reported on the clinical utility of cardiac magnetic resonance imaging at 3 Tesla in the assessment of myocardial function, perfusion and viability, and coronary arteries. The results of these clinical studies are reviewed, as well as emerging applications in myocardial tagging and cardiac spectroscopy.

D005682	Gadolinium	An element of the rare earth family of metals. It has the atomic symbol Gd, atomic number 64, and atomic weight 157.25. Its oxide is used in the control rods of some nuclear reactors.
D006801	Humans	Members of the species Homo sapiens.	Homo sapiens,Man (Taxonomy),Human,Man, Modern,Modern Man
D017202	Myocardial Ischemia	A disorder of cardiac function caused by insufficient blood flow to the muscle tissue of the heart. The decreased blood flow may be due to narrowing of the coronary arteries (CORONARY ARTERY DISEASE), to obstruction by a thrombus (CORONARY THROMBOSIS), or less commonly, to diffuse narrowing of arterioles and other small vessels within the heart. Severe interruption of the blood supply to the myocardial tissue may result in necrosis of cardiac muscle (MYOCARDIAL INFARCTION).

D055414	Myocardial Perfusion Imaging	The creation and display of functional images showing where the blood is flowing into the MYOCARDIUM by following over time the distribution of tracers injected into the blood stream.

D019028	Magnetic Resonance Imaging, Cine	A type of imaging technique used primarily in the field of cardiology. By coordinating the fast gradient-echo MRI sequence with retrospective ECG-gating, numerous short time frames evenly spaced in the cardiac cycle are produced. These images are laced together in a cinematic display so that wall motion of the ventricles, valve motion, and blood flow patterns in the heart and great vessels can be visualized.
