Cardiac MRI: Dobutamine stress myocardial Perfusion Using 3T MRI

Abstract

Cardiovascular disease is important one of the leading cause of death in the United States. Each year, over 1.5 million U.S. residents have myocardial infarctions, roughly one-third of whom die. Although there has been a dramatic reduction in the death rate due to cardiovascular disease over the past 30 years, it still accounts for 22% of all deaths(Thomet al., 2006) Diagnostic imaging has played an important role in the proper assessment and management of coronary artery disease. Advances in rapid magnetic resonance (MR) imaging technology and its application to cardiac imaging have shown that MR imaging has tremendous potential for evaluation of coronary artery disease and cardiac disease in general(Yun et al., 2015) The popular used techniques include stress single-photon emission computed tomography (SPECT), stress echocardiography and stress Cardiac Magnetic Resonance (CMR) account for the vast majority of test
