Key result
FT-CMR shows high intra-observer reproducibility for myocardial strain, peaking with circumferential strain at ~0.96 ICC.
Why the study?
Myocardial strain imaging has potential for clinical application, but the reproducibility and analysis time of FT-CMR need evaluation.
Is feature-tracking cardiovascular magnetic resonance (FT-CMR) reproducible and time-efficient for calculating myocardial strain?

Is feature-tracking cardiovascular magnetic resonance (FT-CMR) reproducible and time-efficient for calculating myocardial strain?
FT-CMR is a highly reproducible and rapid method for assessing myocardial strain, particularly circumferential strain, supporting its potential for clinical application.
Taylor et al. (2013) conducted a cross-sectional in Healthy volunteers (n=20). Feature-tracking cardiovascular magnetic resonance (FT-CMR) was evaluated on Intra-observer and inter-observer reproducibility of myocardial strain. Feature-tracking cardiovascular magnetic resonance demonstrated high intra-observer reproducibility, particularly for circumferential strain (ICC 0.96; 95% CI 0.90-0.99).
