CMR feature tracking using non-rigid, elastic registration demonstrated good to excellent intra- and inter-observer variability for global strain (ICC 0.89-1.00 and 0.74-0.99, respectively), independent of observer expertise.

CMR feature tracking using non-rigid elastic registration is a reproducible approach for global myocardial strain analysis, independent of observer experience, though segmental strain variability remains high.
Morais et al. (2016) conducted an observational in Myocardial pathology (n=21). Cardiovascular magnetic resonance myocardial feature tracking (CMR-FT) using a non-rigid, elastic image registration algorithm vs. Different observers and test-retest acquisitions was evaluated on Intra-observer, inter-observer, and inter-study variability (coefficient of reproducibility and intraclass correlation coefficient) of myocardial strain. CMR feature tracking using non-rigid, elastic registration demonstrated good to excellent intra- and inter-observer variability for global strain (ICC 0.89-1.00 and 0.74-0.99, respectively), independent of observer expertise.
