A detailed analysis of the motion of 11 segments of major abdominal vessels (renal, hepatic, mesenteric, splenic arteries, aorta) during free breathing, as well as during inspiration and expiration breath holds was conducted. The results form a comprehensive reference for motion of the abdominal vasculature that extends the knowledge from previous motion studies. These data should be valuable for those interested in imaging the abdominal vasculature using respiratory-gated or breath-held acquisitions.
