Abstract Two-dimensional (2D) strain analysis is constrained by geometry-dependent
reference directions of deformation (ie radial, circumferential, and longitudinal) following the …

Two-dimensional (2-D) strain (ε2-D) on the basis of speckle tracking is a new technique for
strain measurement. This study sought to validate ε2-D and tissue velocity imaging (TVI) …

BACKGROUND: Different 2-dimensional speckle-based strain techniques have been
developed to overcome the problem of angle dependency with Doppler-based strain …

Right ventricular (RV) function is an independent predictor of cardiovascular adverse events
in patients with multiple cardiopulmonary disease (1). Recently, 2-dimensional (2D) speckle …

Objective The aim of this study is to compare three-dimensional echocardiography strain–
volume analysis with tagging cardiac magnetic resonance (cMR) measurements …

Aims Assessment of left ventricular (LV) systolic function plays a central role in cardiac
imaging. Calculation of ejection fraction (EF) is the current method of choice; however, its …

Abstract Threedimensional (3D) strain maps of the myocardium provide a coordinate
system–independent quantification of myocardial deformation and kinematics. We combine …

Aims Cardiac magnetic resonance (CMR) feature tracking (FT) with steady-state free
precession (SSFP) has advantages over traditional myocardial tagging to analyse left …

Background In prior work, the authors demonstrated that two-dimensional speckle-tracking
(2DST) correlated well but systematically overestimated global longitudinal strain (LS) and …

Measurement of local strain provides insight into the biomechanical significance of viable
myocardium. We attempted to estimate myocardial strain from cine cardiovascular magnetic …
