Fully Automatic Left Atrial Strain Quantification via Multi-task Learning on Cardiac Cine MRI.
BACKGROUND Cardiac magnetic resonance feature tracking (CMR-FT) of left atrial (LA) strain is hindered by thin-wall contouring errors, motion heterogeneity, and temporal drift, while manual or landmark-based methods lack reproducibility and scalability. METHODS We retrospectively collected a multi-center, two-vendor...
