Quantification of vessel branch angle and radius of curvature. (A) The branch angle was the angle between the orthogonal axis of the abdominal aorta and the vessel vector originated from its ostia on the centerline path and extended by 10-mm arclength. Negative angle indicates downward-directed branching. (B) The radius of peak curvature was defined from the circumscribed circle formed by three points (spanning 10-mm) on the vessel path at the location of peak curvature.
