Why the study?
Normal ranges for left atrial strain, strain rate using cardiac magnetic resonance feature tracking, and sphericity index, as well as their comparison with 2D-speckle tracking echocardiography, needed to be established in a healthy population.
Does cardiac magnetic resonance feature tracking provide comparable left atrial strain measurements to 2D-speckle tracking echocardiography in healthy volunteers?
Does cardiac magnetic resonance feature tracking provide comparable left atrial strain measurements to 2D-speckle tracking echocardiography in healthy volunteers?
CMR-FT provides reproducible measurements of LA strain and strain rate that are comparable to volume-gated 2D-STE in healthy volunteers.

Supports volume-gated STE as CMR-comparable for LA strain in healthy volunteers; leaves open validation in disease.
