Figure 1a-d: Different degrees of myocardial contrast using harmonic power Doppler imaging (four chamber view) during continuous infusion of Levovist (R): Arrival of the contrast agent in the right ventricle (a) and complete left ventricular opacification shortly after (b) using triggered imaging every heart cycle (1:1). Complete left ventricular myocardial opacification using higher trigger intervals every 3rd (c) and every 5th (d) cardiac cycle.

Figure 2a-e: Negative bolus destruction reperfusion study using power pulse inversion imaging. First, continuous infusion of a contrast agent is adjusted to achieve full myocardial opacification using real-time imaging at very low emission power (a) (MI = 0.09). After destruction of the microbubbles by a short period of high power imaging (b) (MI = 1.3) myocardial contrast replenishment is recorded at low emission power (c–e) (MI = 0.09). A region of interest (ROI) is placed in the septum and repeated measurements are made at the endsystolic frames. The graph shows the reperfusion curve for this ROI, fitting well to the monoexponential function.
