AIM:To assess the accuracy of three-dimensional contrast-enhanced magnetic resonance angiography (3D CE MRA) inevaluation of the portal vein involvement in patients withhepatic tumors.METHODS:3D CE MRA was performed in 62 patients withhepatic tumors to assess the patency of the main,right andleft portal veins before hepatic surgery.A total of 186 veinswere examined for encasement,occlusion and tumorthrombosis.The results of 3D CE MRA diagnosis were thencorrelated with the surgical-pathological and intra-operativesonographic findings.RESULTS:3D CE MRA correctly detected 48 of 49 involvedand 135 of 137 noninvolved portal veins with the sensitivityof 98%,specificity of 99%,positive predictive value of96% and negative predictive value of 99%.CONCLUSION:3D CE MRA is accurate in evaluation of theportal vein involvement in patients with hepatic tumors.
