实时心肌超声造影利用高能量超声破坏微泡后再充盈速率和平台信号强度反映心肌微循环。该技术操作方便,可同时获得灌注和功能信息,对于检测冠心病、判断冠状动脉狭窄程度、评价心肌存活性、确定危险或梗死区面积、评价梗死后心肌再灌注以及无复流或低灌注现象等提供了重要手段。 Real-time myocardial contrast echocardiography using high-energy ultrasound after the destruction of microbubbles filling rate and platform signal intensity reflect myocardial microcirculation. The technology is easy to operate and can simultaneously obtain perfusion and functional information for the detection of coronary heart disease, to determine the degree of coronary artery stenosis, to assess myocardial viability, to determine the area of ​​risk or infarct size, to assess infarct-reperfusion and no-reflow or hypoperfusion Etc. provides an important means.
