Left atrial (LA) size is a useful measurement in predicting adverse cardiovascular outcomes. The current study compared LA volume accuracy and strain analysis between conventional segmented cine cardiac magnetic resonance (CMR) and single-shot compressed sensing (CS) cine CMR in 31 and 30 patients with and without left ventricular (LV) diastolic dysfunction, respectively. In both techniques, LA passive ejection fraction and passive radial and longitudinal strain showed diagnostic efficacy for LV diastolic dysfunction, and volume accuracies were not significantly different between techniques. CS cine CMR can reliably assess LA volume and strain in patients who are at risk for cardiovascular diseases.
