Establishment and value of multi-slice spiral CT model of hepatic carcinoma in interventional procedure

Objective: To explore the value of multi-slice spiral CTA imaging to interventional transcatheter arterial chemoembolization(TACE) of hepatic carcinoma.Methods: MSCTA and DSA of hepatic artery were sequentially performed in thirty-two patients with malignant tumor of liver,and the interval of these two examinations was 1~7 days.Multi-slice spiral CT model of hepatic carcinoma for interventional procedure was established with volume rendering(VR) technique of CT.According to DSA,the anatomical type of hepatic artery,the origin of the celiac artery and the superior mesenteric artery,the feeding arteries of hepatic tumor were compared with MSCTA.Results: There was good correlation between multi-slice spiral CTA imaging of hepatic carcinoma and DSA in the ability of showing the anatomical type of hepatic artery,the origin of the celiac artery and the superior mesenteric artery,the feeding arteries of hepatic tumor.Multi-slice spiral CTA of hepatic carcinoma before interventional procedure can clearly display the anatomical type of hepatic artery,the origin of the celiac artery and the superior mesenteric artery,the feeding arteries of hepatic tumor.Conclusion: Multi-slice spiral CTA imaging of hepatic carcinoma before interventional procedure can provide effective guidance for TACE of hepatic carcinoma.
