Abstract

Maximum diameter of an abdominal aortic aneurysm (AAA) is themain indication for surgery. This study compared colour duplex ultrasound (CDU) and computed tomography (CT) in assessing AAA diameter. Patients andMethods. Patients were included if they had both scans performed within 90 days. Pearson’s correlation coefficient, paired t-test, and limits of agreement (LOA) were calculated for the whole group. Subgroup analysis of small (6.5 cm) aneurysms was performed. A P value of
