Inter-study repeatability of left ventricular strain measurement using feature tracking on MRI cine images

Feature tracking (FT) is a novel approach for myocardial strain evaluation from standard cine MRI. Conversely to tagging, an original feature of FT is its ability to analyze all heart chambers, independently of their wall thickness. However, few technical challenges, including its inter-study repeatability need to be investigated and this is the aim of our study. We studied 10 healthy individuals (59±9 years), who underwent 2 MRI exams,...
