为探讨多普勒能量组织成像（ＤＰＴＩ）定量分析急性心肌梗塞面积的价值。用该技术测量８条犬实验性急性心肌梗塞面积并和病理染色对照。结果表明：ＤＰＴＩ显示的左室心肌梗塞区面积、心肌总面积和两者的百分与病理ＮＢＴ染色所显示的结果高度相关（ｒ＝０．９１～０．９６，Ｐ均＜０．０１）。因此可将ＤＰＴＩ作为定量分析急性心肌梗塞面积的可靠方法
To explore the value of quantitative analysis of acute myocardial infarction area by Doppler energy tissue imaging (DPTI). The technique was used to measure the area of experimental acute myocardial infarction in eight dogs and to compare with pathological staining. The results showed that the area of left ventricular infarction, the total area of myocardium and the percentages of both were significantly correlated with the results of pathological NBT staining (r = 0.91-0.96, P <0.01) . Therefore, DPTI can be used as a reliable method for quantitative analysis of acute myocardial infarction area
