Low dose gadobenate dimeglumine (0.1 and 0.05mg/kg) used in delayed-contrast enhancement cardiac MRI for myocardial viability was evaluated using early and late acquisition times following injection. 0.1 mg/kg showed efficacy in identifying myocardial infarctions after a minimum 10 minute time delay after injection. Initial results with 0.05 mg/kg also suggests potential efficacy in myocardial viability imaging after a minimum time delay of 10 minutes. Elevated Troponin T >1.0ng/mL trended towards improved identification of infarction before 10 minutes.
