Abstract：Objective This study was designed to compare the accuracy of multi‐detector computed tomography (MDCT) and real‐time 3‐dimensional echocardiography (RT‐3DE) for left atrial (LA) volume and function assessment with magnetic resonance imaging (MRI) .Methods A total of 42 patients underwent MDCT ,MRI and RT‐3DE examina‐tions within 3 days .LAVmax ,LAVmin ,and LAEF data were obtained .Intermotality agreement was tested through Bland‐Altman analysis and paired t test .Interobserver variability was tested through Bland‐Altman analysis .Results For LAVmax ,LAVmin ,and LAEF measurements ,there was no significant difference by MDCT and RT‐3DE in comparison with MRI ( P > 0 .05) .Furthermore ,MDCT and RT‐3DE showed good intermotality agreement with MRI for LA volume and LAEF .For the interobserver variability ,MDCT was best ,then MRI ,followed RT‐3DE .Conclusion MDCT and RT‐3DE can provide highly reliable measurements of LA volume and function and information .However ,MDCT can ex‐amine coronary artery and cardiac function at the same time .
