Clinieal application of two-demensional tissue tracking in pediatric patients / 中国医学装备

A tissue-tracking system can trace myocardial tissue using pattern matching method regardless of Doppler velocity information.The article shows data concerning clinical usefulness of the 2-dimensional tissue tracking(2DTT)technique in pediatric patients.2DTT is able to measure 3 directional(radial,circumferential,and longitudinal)strains of the myocardium in a pediatric population including neonates.Therefore,2DTT has clinical value for determination of normal pediatric cardiac myocardial strain.
