Three-dimensional contrast-enhanced MR angiography in diagnosis of portal vein involvement by hepatic tumors

AIM: To assess the accuracy of three-dimensional contrastenhanced magnetic resonance angiography (3D CE MRA) in evaluation of the portal vein involvement in patients with hepatic tumors.METHODS: 3D CE MlRA was performed in 62 patients with hepatic tumors to assess the patency of the main, right and left portal veins before hepatic surgery. A total of 186 veins were examined for encasement, occlusion and tumor thrombosis. The results of 3D CE NRA diagnosis were then correlated with the surgical-pathological and intra-operative sonographic findings.RESULTS: 3D CE MRA correctly detected 48 of 49 involved and 135 of 137 noninvolved portal veins with the sensitivity of 98 %, specificity of 99 %, positive predictive value of 96 % and negative predictive value of 99 %.CONCLUSION: 3D CE NRA is accurate in evaluation of the portal vein involvement in patients with hepatic tumors.
