Time-intensity curves from images acquired in a patient from regions of interest within cavity blood, normal myocardium, and infarcted myocardium. In all volunteers and in regions of normal myocardium in patients, the myocardial time-intensity curves (squares) were similar to those of blood (open circles) but smaller in magnitude. In regions of infarcted myocardium (triangles), time intensity curves showed hyper enhancement in images acquired more than 2 min post-contrast.
