Application of multislice spiral CT angiography(MSCTA) on diagnosis of hepatocellular carcinoma

ObjectiveTo evaluate the clinical value of multislice spiral CT angiography(MSCTA) on diagnosis of hepatocellular carcinoma.MethodsThe CT images of 70 cases diagnosed hepatocellular carcinoma by clinial and surgery or pathology were collected and analyzed.All cases were underwent triple-phase enhanced MSCT.The data of were transferred to the workstation and post-processed with maximum intensity projection(MIP) and volume reconstruction(VR).The relationship of liver lesions and hepatic blood vessels were analyzed.Results MSCTA could clearly reveal hepatic tumors,feeding arteries or draining veins of some tumors and portal thrombosis.The total of 81 hepatocellular carcinoma foci in 70 patients was found.12 cases of vascular variations was found,The tumor feeding arteries were found in 61 cases.The tumor vasculature was found in 51 cases.Arteriovenous fistula was detected in 9 case.The portal vein invasion was found in 10 cases.The tumor embolus within portal vein was found in 14 cases.The coincidence rate with operation pathology diagnosis was 93.8%.ConclusionMSCTA can directly display tumor foci,feeding arteries,tumor vasculature,portal vein system,which can provide important information and guidance effect for surgical operation and interventional therapy.
