TABLE 3.

The agreement of lumen and vessel wall measurements (ICC values with 95% CI) between automatic and manual segmentation methods and between two manual reads.

ICC (GT2-X) (95% CI)	0.988 (0.986–0.989)	0.951 (0.944–0.956)	0.907 (0.896–0.918)	0.797 (0.773–0.819)
ICC (GT1-GT2) (95% CI)	0.987 (0.985–0.988)	0.926 (0.916–0.934)	0.877 (0.862–0.891)	0.704 (0.671–0.734)
