Speckle Tracking Strain Imaging: Practical Approach for Application

myocardial strain and strain rate imaging: comparison between doppler derived strain imaging and speckle tracking echocardiography

The role of speckle tracking strain imaging in cardiac pacing.

In recent years, concerns have been raised about possible harmful effects of long-term right ventricular (RV) apical pacing. These detrimental effects may be related to changes in left ventricular (LV) mechanics during RV apical pacing. As a consequence, alternative RV pacing sites have been proposed, and in selected patients an upgrade from RV to biventricular pacing may be considered. Novel t...

Ultrasound Speckle Tracking For Strain Estimation

This paper presents an alternative to Elastography by speckle tracking ultrasonic frames quantifying both motion and strain. We combine two similarity measures for varying echographic content including displacement processing, with interframe and trajectory performance measured on extensive synthetic and in vitro data.

Echocardiographic speckle-tracking based strain imaging for rapid cardiovascular phenotyping in mice.

RATIONALE High-sensitivity in vivo phenotyping of cardiac function is essential for evaluating genes of interest and novel therapies in small animal models of cardiovascular disease. Transthoracic echocardiography is the principal method currently used for assessing cardiac structure and function; however, standard echocardiographic techniques are relatively insensitive to early or subtle chang...

Clinical Application of 2D Speckle Tracking Strain for Assessing Cardio-Toxicity in Oncology

Echocardiography has recently undergone innovations due to the availability of deformation parameters as strain, strain rate, torsion and rotation that allow an accurate assessment of myocardial function. Because of this general progress, the importance of myocardial deformation parameters has been highlighted, and some aspects of their clinical and research applications have recently been cons...
