Key result
Magnetic resonance imaging of the thoracic aorta demonstrated acceptable inter-study reproducibility for ascending aortic strain (ICC 0.53) and good reproducibility for descending strain (ICC 0.74).
Observational (n=25)
Effect estimate: ICC 0.53
Absolute Event Rate: 11.53% vs 10.55%
p-value: p=<0.01
MRI using semi-automated ARTFUN software provides a highly reproducible method for assessing aortic structural and functional parameters.

Supports MRI aortic strain assessment in research cohorts; leaves open clinical adoption pending validation.
Noda et al. (2015) reported an observational. Aortic magnetic resonance imaging (MRI) vs. Repeat MRI (test-retest) was evaluated on Inter-study reproducibility of mean ascending aortic strain (ICC 0.53, p=<0.01). Magnetic resonance imaging of the thoracic aorta demonstrated acceptable inter-study reproducibility for ascending aortic strain (ICC 0.53) and good reproducibility for descending strain (ICC 0.74).
