Speckle tracking strain echocardiography: What sonographers need to know!
Journal of the Indian Academy of Echocardiography & Cardiovascular Imaging, 2017 Introduction: Strain is a unitless measurement of dimensional or deformational change; speckle-tracking echocardiography is the most widely used technique to assess strain, with demonstrated clinical utility in a variety of settings.

Speckle Tracking in Intracardiac Echocardiography for the Assessment of Myocardial Deformation [PDF]
IEEE Transactions on Biomedical Engineering, 2009 Intracardiac echocardiography (ICE) has proven to be useful for online anatomical imaging during catheterization. Our objective was to develop a speckle tracking method for myocardial motion estimation from ICE image sequences in order to provide a mean for regional functional imaging.

Assessment Of Left Ventricular Systolic Function By Speckle Tracking Echocardiography In Young Hypertensive Patients [PDF]
Al-Azhar International Medical Journal, 2022 Background: Tissue Speckle Tracking examines speckle aberrations in an echo picture to determine myocardial contractility and relaxation. Reflections, refraction, and dispersion of echo beams generate speckles.

Studying diastology with speckle tracking echocardiography: The essentials
Annals of Cardiac Anaesthesia, 2017 Diastolic dysfunction is common in cardiac disease and an important finding independent of systolic function as it contributes to the signs and symptoms of heart failure. Tissue Doppler mitral early diastolic velocity (Ea) combined with peak transmitral early diastolic velocity (E) to obtain E/Ea ratio provides an estimate of the left ventricular (LV ...
