超声斑点追踪技术不受心脏整体运动影响且无角度依赖性,是评价心脏短轴运动的新方法。本文对超声斑点追踪技术在评价正常及病理状态下心脏短轴运动的应用作一综述。
Ultrasound speckle tracking is independent of whole heart motion and is angularly independent and is a new method to evaluate short-axis cardiac motion. In this paper, the application of ultrasound speckle tracking in the evaluation of cardiac motion under normal and pathological conditions is reviewed.
