Clinical feasibility and validation of 3D principal strain analysis from cine MRI: comparison to 2D strain by MRI and 3D speckle tracking echocardiography

Estimating 3D Strain from 4D Cine-MRI and Echocardiography: In-Vivo Validation

The quantitative estimation of regional cardiac deformation from 3D image sequences has important clinical implications for the assessment of myocardial viability. The validation of such image-derived estimates, however, is a non-trivial problem as it is very difficult to obtain ground truth. In this work we present an approach to validating strain estimates derived from 3D cine-Magnetic Resona...

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

[2D and 3D speckle tracking echocardiography: clinical application].

WSTĘP Wizualna ocena zaburzeń kurczliwości to jedno z trudniejszych zagadnień echokardiograficznych, wymagające dużego doświadczenia. Półilościowa ocena kurczliwości związana bywa z różnicami w interpretacji między ekspertami oraz ze zmiennością interpretacji nawet przez tego samego echokardiografistę. Krokiem ku obiektywizacji oceny regionalnej funkcji skurczowej jest wprowadzenie technik iloś...

Temporal 3D Lagrangian strain from 2D slice-followed cine DENSE MRI.

A quantitative analysis of myocardial mechanics is fundamental to the understanding of cardiac function, diagnosis of heart disease and assessment of therapeutic intervention. In clinical practice, most cardiac imaging analyses are performed in 2D because of the limited scan time available. However, the obtained information from a 2D measurement is limited. This study presents a method to obtai...
