多层CT门静脉造影在肝脏肿瘤中的临床应用

目的探讨门静脉多层CT成像在临床中的应用价值.方法收集资料完整的病例57例,其中肝硬化患者12例,原发肝脏肿瘤18例,转移性肝脏肿瘤21例,肝外肿瘤累及门静脉6例.术前行多层CT(MSCT)门静脉造影,行多种方法重建.同时将影像检查与术中结果进行对照,分析MSCTP的诊断价值.结果MSCTP可显示门静脉5～6级分支,门静脉的解剖分型显示清晰.肝硬化门静脉增粗,侧支循环开放情况显示清晰.肝内肿瘤对门静脉分支浸润表现为包绕、穿行、推移.肝外肿瘤对门静脉属支包裹或浸润6例.所得影像结果与外科术中所见具有较高的一致性.结论多层CT门静脉造影具有较高的临床应用价值,对外科进行术前判断,术后评估具有重要的意义.

Application of multi-slice CT portography in liver carcinoma

Objective The aim was to evaluate the role of multi-slice CT portography in clinical. Methods Fifty seven cases which have been exanimated by MSCT portography were collected. In these cases, including hepatic cirrhosis patient 12 cases case, primary hepatic tumor 18 cases, metastatic hepatic tumor 21 cases, and the tumor outside liver which involved portal vein system 6 cases. We used MSCT portography for preoperative diagnosis and reconstructed with three methods. At same time, we analyzed these data before and after operation. Results Branches of 5 - 6 scale portal vein and anatomy types displayed clearly. In hepatic cirrhosis group, the portal vein became thicken, and portosystemic collaterals opened. For hepatic tumor,the branch of portal vein was wrapped, cut in and dislodged by tumor tissue. For tumor liver the subordinate branch of portal vein was packaged or infiltrated. All of imaging display was coordirated with the manifastation in surgery. Condusion the multi-slice CT portography has important clinical value in diagnosis of primary and secondary liver carcinoma.
