Figure 7 Agreement Between MSCT and Echocardiography

Bland-Altman plot analysis revealed a good agreement between multislice computed tomography (MSCT) and echocardiography (ECHO) for the assessment of aortic annulus diameter. The difference between each pair (y axis) is plotted against the average value of the same pair (x axis). Mean difference was 1.9 mm (solid line), 95% confidence interval –2.8 to 6.6 mm (dotted lines).
