This study sought to enhance the work detailed in Poster I (4458) by investigating if contrast agent dose/kg, heart rate, ejection fraction, left ventricular mass and signal intensity in the blood pool of the LV during FPPI impact on the peak signal intensity detected in the myocardium during initial enhancement in a cohort of normal healthy volunteer and a cohort of cardiac patients.
