Feasibility and accuracy of a novel automated three-dimensional ultrasonographic analysis system for abdominal aortic aneurysm: comparison with two-dimensional ultrasonography and computed tomography

摘要

A representative case comparing the analysis of aortic diameter, area, and thrombus volume by different tests in abdominal aortic aneurysm: (a) aorta computed tomography, (b) two-dimensional (2-D) longitudinal, (c) 2-D axial images, and (d) three-dimensional (3-D) automated software analysis. The yellow circle marks the intima-lumen boundary; the red circle, the media-adventitia interface; and blue circle, the thrombus boundary in the automated 3-D ultrasonographic software analysis in D. The red line represents the maximum diameter of the vessel, and the blue line represents the maximum diameter of the non-thrombosed lumen
