Reproducibility and its confounders of CMR feature tracking myocardial strain analysis in patients with suspected myocarditis

ConclusionIn a large clinical cohort, we could show CMR-FT yields excellent inter-reader and intra-reader reproducibility. Multi-parametric CMR-FT of the right and left ventricles appears to be a robust tool in cardiovascular patients referred to CMR.Clinical trial registration.ClinicalTrials.gov Identifier: NCT03470571, NCT04774549.Key Points•Cardiovascular magnetic resonance feature tracking (CMR-FT) is an emerging technique to measure myocardial strain in cardiovascular patients referred for CMR; however, the evaluation of its reproducibility in a large cohort has not yet been performed.•In a large clinical cohort, CMR-FT yields excellent inter-reader and intra-reader reproducibility for both left and right ventricular systolic and diastolic parameters.•Arrhythmia and pericardial effusion compromise agreement of select FT parameters, but poor ejection fraction does not.
