Overview
Abdominal MRI may be helpful in the diagnosis of portal vein thrombosis. Findings on MRI diagnostic of portal vein thrombosis include filling defect that partially or completely occludes the vessel lumen in the portal venous phase, clot appears isointense on T1- weighted images, and usually has a more intense signal on T2 images, and presence of varices.
MRI
- Abdominal MRI may be helpful in the diagnosis of portal vein thrombosis. Findings on MRI diagnostic of portal vein thrombosis include:[1][2][3]
- Filling defect that partially or completely occludes the vessel lumen in the portal venous phase
- Clot appears isointense on T1- weighted images, or hyperintense if recent, and usually has a more intense signal on T2 images
- Presence of varices
- Verify the correct function of surgical shunts
