Comprehensive 4D flow imaging encompassing the entire upper abdominal vasculature would facilitate diagnosis of complex disease processes in the hepatic and splanchnic vasculature. An efficient 4D velocity mapping approach using 5-point PC-VIPR was applied to assess the splanchnic and hepatic vasculature in 24 participants, many with portal hypertension. This approach may be advantageous in the assessment of liver disease because hepatic and splanchnic flow can change dramatically in the presence of portal hypertension. Comparison with contrast-enhanced imaging and analysis of complex flow patterns analysis will be presented.
