Overview
Abdominal CT scan may be helpful in the diagnosis of portal vein thrombosis. Findings on CT scan suggestive of hyperattenuating material in the portal vein lumen, nonenhanced intraluminal-filling defect, Lack of luminal enhancement, increased hepatic enhancement in the arterial phase and decreased hepatic enhancement in the portal phase.
