1 Ultrasound-determined diameter measurements are more accurate than axial computed tomography after endovascular aortic aneurysm repair  Sukgu M. Han, MD, Kaushel Patel, MD, Vincent L. Rowe, MD, Susana Perese, BS, RVT, Aaron Bond, PhD, Fred A. Weaver, MD, MMM  Journal of Vascular Surgery  Volume 51, Issue 6, Pages (June 2010) DOI: /j.jvs Copyright © 2010 Society for Vascular Surgery Terms and Conditions

2 Fig 1 The ultrasound-determined anteroposterior and transverse maximal aortic diameter is shown. The larger of the two measurements was recorded as the major axis measurement, and the smaller as the minor axis measurement.

3 Fig 2 The computed tomography-determined (left) anteroposterior and transverse maximal aortic diameter and (right) the major and minor axis aortic diameter are shown. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2010 Society for Vascular Surgery Terms and Conditions

4 Fig 3 Major and minor aortic diameters are shown as determined by centerline M2S reconstruction. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2010 Society for Vascular Surgery Terms and Conditions

5 Fig 4 Left, A linear correlation is shown between computed tomography (CT) centerline images and the minor axis measured on ultrasound (US) imaging. Right, A Bland-Altman plot shows US minor and CT centerline diameter measurements. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2010 Society for Vascular Surgery Terms and Conditions

6 Fig 5 Left, A linear correlation is shown between the computed tomography (CT) centerline diameter and the ultrasound (US) major axis diameter. Right, A Bland-Altman plot shows US major and CT centerline diameter measurements. Journal of Vascular Surgery  , DOI: ( /j.jvs ) Copyright © 2010 Society for Vascular Surgery Terms and Conditions

7 Fig 6 Left, A linear correlation is shown between computed tomography (CT) centerline diameter and minor axis diameter measurements. Right, A Bland-Altman plot is shown of CT centerline diameter and minor axis diameter measurements.
