A deep learning based method for left ventricular strain measurements: repeatability and accuracy compared to experienced echocardiographers.

Journal: BMC medical imaging
PMID: 39528980

Abstract

BACKGROUND: Speckle tracking echocardiography (STE) provides quantification of left ventricular (LV) deformation and is useful in the assessment of LV function. STE is increasingly being used clinically, and every effort to simplify and standardize STE is important. Manual outlining of regions of interest (ROIs) is labor intensive and may influence assessment of strain values.
