Discussion

This multicenter analysis reveals inter-software agreement on strain measurements in CMR, suggesting the need for standardization.

Good intra- and inter-observer reproducibility for strain measurements was found across different CMR scanners.
Inter-software agreement was low for myocardial strain values, particularly GLS and GRS, indicating disparity between software platforms.
The study assessed CMR FT strain and ejection fraction comparability using various MR scanners and analytical software.
Findings suggest a need for improved standardization between different CMR software solutions for better clinical utility.

Goetze et al. (2025) studied this question.
