Purpose. This study compared cardiac computed tomography (CT) and two-dimensional transthoracic echocardiography (ECC) for assessing left ventricular ejection fraction (LVEF) using real-world data from a large patient population. Materials and methods. We studied 450 patients (284 males; mean age 64 +/- 12 years; range 12-88) who underwent CT and ECC due to suspected coronary artery disease. For CT, we used multiphase short-axis reconstructions and evaluated them with a dedicated software tool that uses Simpson's rule to compute LV volumes. For ECC, computation was based on the biplane Simpson's method. Results in terms of EF were compared with the paired Student's t test, Pearson's correlation coefficient (r), and Bland-Altman analysis. Results. EF was 52%+/- 15% for CT and 55%+/- 13% for ECC. Statistically significant differences, albeit with correlation, were observed between the measurements (r=0.71; p50% and overestimated in those with EF 35%-50% and
