Semiautomatic Volumetry of Low Attenuation of Thoracic Aortic Plaques on Curved Planar Reformations Using MDCT Angiographic Data with 0.5 mm Collimation

Figure 4

Bland–Altman plot for volumetry of the thoracic aortic plaque.

(a) Bland–Altman plot for the intraobserver comparison of plaque volume. Outer dot lines: 95% CI. Inner dot lines: bias

(b) Bland–Altman plot for the interobserver comparison of normalized plaque volume measurements by the two observers. Outer dot lines: 95% CI. Inner dot lines: bias
