AT the present time actively developed vesche CTBA , having contrasting properties at ultrasound conditions . They can be used for perfusion evaluation and the function of the myocardium , as well as for identify viable myocardium . Evaluation of coronary blood flow is possible . by analysis time curves intensity to ultrasound signal .
Ultrasound characteristics of heart tissue
With the help of this technique is possible differential – rentsirovka different myocardial conditions : ischemia , hibernation and cicatricial lesion . In addition , the analysis of the reflected frequencies allows us to distinguish between acute and chro -ethnic ischemia . More precise definition of the boundaries of the endocardial allow better assessment of local contraction reversibility infarction .
Using modern software both sintered possible to evaluate the jet Keturah and LV function at three dimensions . This approach allows not to lean on various geometric modelsforms LV , which is especially important in patients after Perene hay myocardial infarction . Three-dimensional Echocardiography more accurately determines the size , the localand global contractility of the left ventricle . Serial determination of LV volumes in valvular pathology allows precise define moment for surgical correction of blemish .
