目的:探讨MSCT肝癌介入手术模型在肝动脉化疗栓塞术中的价值。方法:对32例肝恶性肿瘤患者,先后行肝动脉MSCTA和DSA检查,两者间隔时间不超过1周。利用CT的容积再现技术建立MSCT肝癌介入手术模型,以肝动脉DSA图像为金标准,对比分析了肝动脉解剖类型、腹腔干或肠系膜上动脉的起源、肝恶性肿瘤的供血动脉。结果:MSCT肝癌介入手术模型与DSA在显示肝动脉的解剖类型、腹腔干或肠系膜上动脉的起源、肝恶性肿瘤的供血动脉有较好的一致性,可清晰地显示肝动脉的解剖类型、腹腔干或肠系膜上动脉的起源、肝癌的供血动脉。结论:MSCT肝癌介入手术模型能为肝动脉化疗栓塞术提供有效的指导。
Objective: To investigate the value of interventional MSCT in the hepatic artery chemoembolization. Methods: Thirty-two patients with hepatic malignant tumor underwent hepatic artery MSCTA and DSA examinations, with an interval of no more than 1 week. CTCT volume reconstruction technique was used to establish a liver cancer interventional model for MSCT. The DSA images of the hepatic artery were used as the gold standard to analyze the anatomic types of hepatic artery, the origin of the celiac trunk or superior mesenteric artery, and the donor arteries of hepatic malignancies. Results: The interventional model of MSCT hepatocarcinoma was in good agreement with DSA in displaying anatomic types of hepatic artery, the origin of celiac trunk or superior mesenteric artery, and the feeding artery of hepatic malignant tumor. The anatomical type of hepatic artery could be clearly displayed, The origin of stem or mesenteric artery, hepatic artery feeding. Conclusion: The interventional model of liver cancer by MSCT can provide effective guidance for hepatic artery chemoembolization.
