Figure 3 Real-time multislice imaging and three-dimensional rendering during endograft positioning. In the left column, real-time magnetic resonance imaging multislice axial, sagittal, and coronal images shown simultaneously facilitate precise device positioning. Concomitant three-dimensional rendering on the right integrates multislice information. Positioning three axial slices at the caudal renal artery origin, the middle of the aneurysm, and the aortic bifurcation, respectively, allows simultaneous capture of the most important anatomy for device placement. The coronal and sagittal slices provide an overall "bird’s eye" view of the aorta. Orientation markers indicate: S = superior, I = inferior, A = anterior, P = posterior, R = right, L = left. Blue arrow indicates aneurysm.
