The objection of this study was to determine whether a method of harmonic imaging could improve the myocardial contrast after injection of Albunex and Levovist. Two dogs were imaged harmonic mode from transdiaphragm approach (transmit at 2.5 MHz and received at 5.0 MHz). Albunex (0.22 ml/kg) and Levovist (400 mg/ml x 2 ml) was injected intravenously for each dog. Venous injection of Albunex coupled with harmonic imaging produced only coronary flow. Venous injection of Levovist coupled with harmonic imaging produced myocardial opacification. It is possible that venous injection of Levovist coupled with harmonic imaging method will also useful in studying myocardial perfusion.
本研究的目的是确定一种谐波成像方法在注射白蛋白微球和Levovist后能否改善心肌对比。对两只狗经膈途径采用谐波模式成像（发射频率2.5MHz，接收频率5.0MHz）。每只狗静脉注射白蛋白微球（0.22ml/kg）和Levovist（400mg/ml×2ml）。白蛋白微球静脉注射联合谐波成像仅产生冠状动脉血流。Levovist静脉注射联合谐波成像产生心肌显影。Levovist静脉注射联合谐波成像方法可能也有助于研究心肌灌注。
