Fig. 4From: Comparative assessment of coronary physiology using transthoracic pulsed-wave Doppler and myocardial contrast echocardiography in ratsRepresentative time course of contrast activity in the lumen of the left ventricle. Shown are systolic gated modified parasternal long axis images that were acquired during nonlinear contrast imaging at the time of contrast agent arrival, i.e., 0 s (a), 1 s (b), and 10 s (c) after contrast agent arrivalBack to article page
