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,是评价心肌扭转运动的新的量化指标。本文对斑点追踪技术在评价正常及病理状态下心脏的扭转运动形式中的应用等问题进行综述,表明斑点追踪技术是检测心肌扭转形变特征的可靠方法,将具有广阔的应用前景。
Ultrasound speckle tracking is not affected by global heart motion and is angularly independent, and is a new quantitative measure of myocardial torsion. This review summarizes the application of speckle tracking in the assessment of cardiac torsion motion under normal and pathological conditions. It shows that speckle tracking is a reliable method for detecting myocardial torsional deformation and will have broad application prospects.
