摘要 目的 :探讨多层螺旋CT肝脏动脉早期扫描CT血管造影 (MSCTA)在中晚期肝癌的临床应用价值。方法 :63例临床确诊的中晚期肝癌病例 ,用TriggerBolus对比剂示踪软件行自动触发全肝动脉早、晚期 (一次屏气完成 )和门脉期扫描 ,动脉早期图像数据经后处理获得肝脏CT血管造影图像。分析肝脏及癌肿血供系统MSCTA表现 ,以及静脉癌栓、动静脉瘘的MSCTA表现。结果 :动脉早期扫描MSCTA能完整显示中晚期肝癌肝脏及癌肿供血动脉起源、形态、数目 ,显示动静脉瘘征象优于标准肝脏双期扫描。结论 :动脉早期扫描MSCTA在中晚期肝癌具有良好的临床应用前景 。 Objective:To investigate the clinical application of early arterial phase multislice CT angiography (MSCTA) of hepatic vessels in evaluation of middle or advanced stage hepatocellular carcinoma.Methods:Trigger Bolus program was used to carry out MSCTA in early and late arterial phases and portal vein phase with single breath holding.Hepatic vessels were reconstructed from the original images of early arterial phase by post processing.The blood supply of tumor and normal liver tissue and the appearances of venous thrombosis and arteriovenous fistula were analyzed.Results:The MSCTA with early arterial phase could perfectly display the origin,shape and amount of feeding vessels to normal liver tissue and tumor in middle or advanced stage hepatocellular carcinoma. It had the ability of displaying the arteriovenous fistula better than that in conventional dual phased liver scanning.Conclusion:MSCTA of hepatic vessels with early arterial phase acquisition using multislice helical CT in middle or advanced stage hepatocellular carcinoma has favorable and promising application. It can be used as an imaging method for comprehensive assessment of the hepatocellular carcinoma before treatment.
