Starting 30 minutes before the cardiac MRI scan (CMR), the subjects will take a 16 mg tablet of ondansetron by mouth. CMR imaging will subsequently take place and then EVP1001-1 will then be administered approximately 15 minutes into the scan for contrast enhanced images. EVP1001-1 will be administered intravenously over approximately one minute. The subjects will each receive 0.28 mL/kg of EVP 1001-1. All subjects will be monitored closely from before ondansetron administration until their discharge from the imaging center. Following MEMRI, delayed-enhanced MRI (DEMRI) is performed using 0.2mmol/kg.
