Abstract：Objective: To evaluate the value of liver acquisition with volume acceleration(LAVA) MR sequence in the diagnosis and classification of primary Budd-Chiari syndrome(BCS). Methods: Twenty-five patients with BCS underwent MR scanning, LAVA was performed. Image quality and the demonstration of hepatic vein(HV), inferior vena cava(IVC) and collaterals were evaluated. Results: Of the 25 patients, there were 14 cases who had demonstration of IVA stenosis, among whom 12 cases had occlusion and segmental stenosis, 2 had memebranous stenosis. Seven cases had obstruction of hepatic vein, mixed type obstruction in 4 cases. Eighteen cases had widening of accessory hepatic vein, 22 cases had extrahepatic collateral vessels and 21 cases had intrahepatic collateral vessels. Conclusion: Normal anatomy of IVC and HV could be clearly depicted on LAVA MR sequence, which is valuable in the site of stenosis, the extent of primary BCS, and the collateral pathways and classification as well demonstrating.
