1 Morphologic evaluation of ruptured and symptomatic abdominal aortic aneurysm by three-dimensional modeling  An Tang, MD, MSc, Claude Kauffmann, PhD, Sophie Tremblay-Paquet, MD, Stéphane Elkouri, MD, Oren Steinmetz, MD, Florence Morin-Roy, MD, Laurie Cloutier-Gill, MD, Gilles Soulez, MD, MSc  Journal of Vascular Surgery  Volume 59, Issue 4, Pages e3 (April 2014) DOI: /j.jvs Copyright © 2014 Society for Vascular Surgery Terms and Conditions

3 Fig 2 A, Three-dimensional (3D) volume rendering in 56-year-old male with ruptured abdominal aortic aneurysm (AAA), shows a high bulge location (arrow) close to the rupture site, indicated by segmentation of contrast extravasation (red). B, 3D volume rendering in control 71-year-old male shows a low bulge location (arrow) is concordant with the location of the maximal diameter (Dmax; arrow), indicated by a red circle.

4 Fig 3 Receiver operating characteristic (ROC) analysis of two models for distinguishing case and control subjects based on gender and maximal diameter (Dmax) alone (model A) and based on gender, Dmax, bulge location, and mean averaged area (model B). The inclusion of two geometric indices to the traditional model showed a trend toward improvement (P < .001).
