【Abstract】Objective To investigate the appropriate reconstruction techniques of multidetectorrow spiral CT angiography (MDCTA) to depict the collateral vessels in cavernous transformation of the portal vein (CTPV) caused by tumor thrombosis of hepatocellular carcinoma (HCC).
Methods MDCTA scanning was performed during the portal venous phase after intravenous contrast materials in 18 HCC patients with CTPV induced by tumor thrombosis. Raw data were reconstructed with thin slice thickness followed by 2D and 3D angiographic reconstruction methods, including maximum intensity projection(MIP), shade surface display （SSD） and volume rendering technique(VRT).
Results MDCTA with MIP reconstruction accurately depicted both the tumor thrombus within the portal vein and the collateral vessels of CTPV including the biliary (cystic vein and pericholedochal veinous plexus) and the gastric (left and right gastric veins) branches. However, VRT and SSD methods did poorly in showing the tumor thrombus and the collateral vessels.
Conclusion MDCTA with MIP reconstruction is the method of choice to evaluate the collateral vessels of CTPV.
