摘要
目的：探讨磁共振LAVA技术对Budd-Chiari综合征显示及其分型价值。方法：25例Budd-Chiari综合征患者行MRI检查，均采用肝脏加速容积采集序列（LAVA），分析图像质量及显示肝静脉、下腔静脉和侧支循环。结果：14例下腔静脉型，其中12例下腔静脉闭塞或狭窄，2例下腔静脉腔内阻塞性隔膜；肝静脉型7例，混合型4例。副肝静脉增粗18例，肝内侧支循环22例，肝外侧支血管形成21例。结论：磁共振LAVA技术能清楚显示下腔静脉、肝静脉的正常解剖和各种病变，对Budd-Chiari综合征病变的程度、部分、侧支血管分布及分型具有较高的诊断价值。
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.
