摘　　要：目的:探讨静脉声学造影后二维图像评价正常兔左心室收缩功能的可行性。方法:20只兔经胸应用自制声学造影剂,观测注入前后左心室心内膜面显示的变化,对比左心室心内膜面节段改善情况。造影后应用平面法测量左心室收缩功能。并与应用M超测定收缩功能参数加以比较。结果:应用造影剂后可获得兔的清晰心腔内膜图像,因此可以应用Simpson法测量左心室收缩功能。结论:静脉声学造影评价左心室收缩功能是可行的,可以在动物实验中加以应用。Objective To investigate the feasibility of two dimensional images in detecting rabbit left ventricular systolic function. Methods Twenty rabbits were injected acoustic contrast via vein and detected the left ventricular systolic function. Results The two dimensional images of left ventricular chamber were obtained after injection of acoustic contrast. Left ventricular systolic function was detected with Simpson method. Conclusion The detection of rabbit left ventricular systolic function with acoustic contrast is feasible.
