Quantitative Aortic Distensibility Measurement Using CT in Patients with Abdominal Aortic Aneurysm: Reproducibility and Clinical Relevance

Table 3

Reliability of distensibility measurements at distinct locations in 54 patients with AAA.

	Level 1.	Level 2.
Intraobserver reliability
Intraclass correlation coefficient	0.92	0.85
Bland-Altman (10^−5 Pa^−1)
Interobserver reliability
Intraclass correlation coefficient	0.89	0.79
Bland-Altman (10^−5 Pa^−1)

Note. AAA, abdominal aortic aneurysm.
Level 1, immediately below the lowest renal artery. Level 2, at the level of maximal aneurysm diameter.
