Cardiovascular magnetic resonance imaging is a powerful technology that offers a comprehensive imaging approach to ischemic heart disease. A major focus of our work is on developing clinical applications of cardiovascular MRI. Active clinical protocols include developing a comprehensive MR exam for clinical trials in peripheral arterial disease including atherosclerotic plaque imaging and calf muscle perfusion and energetics at peak exercise.
Other clinical studies include quantitative myocardial perfusion imaging in microvascular coronary disease, predicting the development of LV dysfunction from chemotherapeutic agents, quantitative myocardial functional imaging as a measure of dyssynchrony in heart failure, coronary artery and wall imaging, and imaging of left atrial structure and mechanics.
