MRI和超声诊断Budd-Chiari综合征的对比研究

Comparison of MRI and sonography in diagnosis of Budd-Chiari syndrome

目的 比较MRI和超声在Budd Chiari综合征 (BCS)分型诊断中的应用价值。方法 回顾性分析 5 1例BCS的术前超声、MRI和血管造影结果 ,以血管造影结果为标准 ,比较MRI和超声显示下腔静脉 ,肝静脉 ,副肝静脉 ,肝内、肝外侧支血管情况。结果 术前超声对血管内膜性病变的确定优于MR(P <0 0 5 ) ;对伴副肝静脉形成肝静脉型正确分型强度相对数分别为 17 65 %和 61 5 4% ,两者有差异 ;超声对肝内侧支血管的显示优于MR(P <0 0 1) ;MR对肝外侧支血管的显示优于超声 (P <0 0 1)。结论 超声是BCS诊断的首选方法 ,而MR与超声在BCS的分型诊断上有很大的互补性。BCS的分型诊断应先行超声检查 。

Objective To compare the value of MRI and sonography in diagnosis of Budd Chiari syndrome. Methods The MRI, sonographic and venographic data of 51 cases with Budd Chiari syndrome were studied retrospectively. With the findings by venography were regarded as criterions, the findings of inferior vena cava (IVC), hepatic veins (HV), accessory hepatic veins, intra and extrahepatic collateral vessels on the MRI and sonography were compared. Results Sonography was better than MRI in confirming the membranous changes( P <0 05). The percentage of correct on depicting accessory hepatic veins in hepatic vein obstruction were 17 65% and 61 54% respectively in sonography and MRI with obvious difference. Sonography was good at showing intrahepatic collateral vessels, while MRI at displaying extrahepatic collateral vessels, both having a significant difference with the other one ( P <0 01). Conclusion Though sonography is still preferred in diagnosis of Budd chiari1syndrome, it is recommend that the diagnosis should be performed with sonography then followed by MRI since MRI and sonography are complementary in the typing of the syndrome.
