Dr. Arai is internationally recognized for his expertise in cardiovascular magnetic resonance (CMR) imaging. Dr. Arai’s research uses advanced cardiovascular imaging to improve our understanding of myocardial ischemia and infarction. Close collaborations with physicists and engineers have led to a series of technical developments that are of interest to a wide range of cardiovascular problems. Major projects have included the first studies validating the use of CMR in evaluating patients with chest pain presenting to the emergency department. His laboratory has developed methods for imaging and quantifying the extent of myocardial infarction, work that has translated from a cellular level to patients. Using those methods, an epidemiology study proved documented the adverse prognostic significance of silent myocardial infarctions in about 950 subjects in Iceland. The lab is well known for developing MRI methods capable of imaging the ischemic area at risk associated with acute myocardial infarction. The group has developed and methods to quantify myocardial perfusion at a resolution of approximately 75 microliter pixels of myocardium, a method that is more accurate than standard clinical interpretations and semi-quantitative analysis methods. The lab has also developed methods capable of quantifying the extracellular volume fraction, a measurement capable of detecting diffuse myocardial fibrosis or edema. Dr. Arai runs an Advanced Cardiovascular Imaging Fellowship Training program at the National Institutes of Health.
