Advances in determining abdominal aortic aneurysm size and growth

Figure 2 Two abdominal aortic aneurysms are presented after three dimensional reconstruction of the computed tomography images. In the left panels cross sections are perpendicular to the y-axis of the CT scanner coordinator system (axial), while in the right panels cross-section are perpendicular to the centerline of flow (orthogonal). Large discrepancies between methods may be encountered in case of high regional asymmetry as in case B. CT: Computed tomography.
