The clinical application of hepatic artery multi-spiral computed tomographic angiography(MSCTA)

Objective:To assess the clinical utility value of hepatic artery multi-slice spiral computed tomographic angiography(MSCTA) and threedimensional reconstruction(3D) techniques.Methods:The hepatic arterial phase CT angiography were performed in 95 patients,including hepatocellular carcinoma(n=22),hepatic hemangioma(n=12),metastatic hepatic carcinoma(n=12),AVM(n=1), FNH(n=1) and intrahepatic bile duct adenoma(n=1).Fifteen cases were performed hepatic arterial DSA at the same time and used as reference.Results:MSCTA and 3D images could clearly show hepatic artery as well as variants.There was no difference between MSCTA and DSA.It could also show feeding artery and tumor vessel of hepatic tumor.Conclusion:3D CT arteriography is as accurate as angiography in the assessmnt of celiac and big hepatic arterial anatomy.It is also safer,more convenient and more easily tolerated.Hepatic arterial SCTA and 3D images have high clinical value.
