This work was supported by the Whitaker Foundation, the Keck Foundation, the Falk Medical Trust, the Veterans Administration, and NHLBI 19-298. I acknowledge Stephen Aylward in the Medical Image Display and Analysis Group at the University of North Carolina at Chapel Hill for kindly providing the images of Fig. 2, Johan Reiber and Gerhard Koning in the Department of Radiology at Leiden University Medical Center for the stenosis severity analysis software image of Fig. 3, and Andreas Wahle in the Department of Electrical Engineering at the University of Iowa for the angiographic images and reconstruction of Fig. 4. None of the studies would have been possible without all the other members of our group: Bob Molthen, Steve Haworth (Fig. 17), Chris Wietholt, Chris Hanger, and especially Kelly Karau, who performed most of the data analysis and provided Figs. 9, 10, 12, 13, 14, 16, and 18, and Chris Dawson, who taught me most of what I know about arterial tree morphometry and with whom any good ideas put forth in this chapter originated.
