Rationale And Objectives: The authors evaluated the potential of SonoVue, a new echo contrast agent, for the detection of myocardial perfusion abnormalities using intermittent harmonic power Doppler (IHPD) imaging and different pulse repetition frequencies (PRFs).
Methods: Experiments were performed in vitro (in a tissue-mimicking phantom) and in vivo (in minipigs) in harmonic power Doppler using an ATL HDI 3000 with second harmonic software. SonoVue was injected intravenously in an auricular vein in bolus (dose range 0.
Rationale And Objectives: We evaluated the potential of BR14, a novel gas-based echo contrast agent, for gray-scale liver imaging and VX2 tumor detection/delineation in the conventional and harmonic imaging modes.
Methods: A single dose (0.2 mL/kg) of BR14 was administered to eight VX2 tumor-bearing rabbits.
Rationale And Objectives: The basic characteristics of BR1, a novel echo contrast agent based on stabilized sulfur hexafluoride (SF6) microbubbles have been evaluated.
Methods: The authors determined the physicochemical properties (bubble concentration, bubble size distribution, resistance to pressure, and stability) and the acoustic properties (backscatter and attenuation coefficients) of BR1. The diagnostic value of BR1 was evaluated further in minipigs.
