Content-time curves for left ventricular blood pool and myocardial tissue regions of interest detected by MRI after bolus injection of polylysine-Gd-DTPA into left atrium of a closed-chest dog. Curves include 3 images (A–C) shown in Fig. 3. Anterior wall region was in stenotic left anterior descending coronary artery perfusion territory and shows reduced and delayed indicator kinetics. Posterior wall region was perfused normally and shows more typical kinetics.
