St. Louis, Mo. (June 9, 2014) – Ischemic heart disease, a narrowing of the arteries supplying blood to the heart, is a leading cause of death throughout the world. A hybrid molecular imaging technique called positron emission tomography and magnetic resonance (PET/MR) imaging, which tells doctors vital information about cardiac and arterial function, has been found to be an effective molecular imaging tool for detecting coronary artery disease (CAD), say researchers at the Society of Nuclear Medicine and Molecular Imaging's 2014 Annual Meeting.
