Maximal contrast to tissue ratio. The maximal contrast to tissue ratio (dB) value (n = 38) and its associated mechanical index (brackets) for each contrast agents (Plain PVA (light gray), PVA Type A (gray), PVA Type B (beige) and SonoVue® (black)) observed with the different contrast sequences (PI=pulse inversion, PM=power modulation, PPI=power pulse inversion, CPS=contrast pulse sequence). Negative CTR-values indicate that the tissue response exceeded the response from the CA. The concentration of the CAs was 105 microbubbles/ml.
