    Abstract:
    OBJECTIVE: To evaluate three dimensional dynamic contrast-enhanced magnetic resonance angiography (3D-DCE MRA) in diagnosis of cavernous transformation of portal vein (CTPV). METHODS: Twenty-four patients with CTPV underwent 3D-DCE MRA examinations and the reconstructed images were retrospectively analyzed. A series of clinical, laboratory and imaging studies were performed on all these cases. Among all cases 14 underwent operations and 2 with hepatocellular carcinoma complicated portal thrombosis received transhepatic artery chemoembolization. RESULT: The CTPA was located in the main trunk in 10 cases, in both the main trunk and left/right branches in 8, and in left or right branches of the portal vein in 4. In the remaining 2 cases CTPA was located at the level of superior mesenteric vein. MRA revealed multiple circuitous collateral veins striding over obstruction to extend into the liver in 9 cases,and in 7 it simultaneously showed streaky or dot-like low signal intensities representing thrombi in the extensively dilated network of portal system. MRA did not clearly demonstrate the structure of the portal vein but only showed multiple sinuous network of venous collaterals strangling together in 6 cases. In 15 cases it also showed the route and distribution of multiple hepatofugal venous collaterals. CONCLUSION: 3D-DCE MRA can provide adequate information about the site and severity of CTPA.
