摘要
目的探讨C臂CT技术在肝癌介入治疗中的应用。方法 77例选择性肝动脉化疗栓塞患者治疗后作C臂CT。其中13例化疗栓塞前后均作C臂CT并利用其Integris3D-RA工作站行三维重建,然后对栓塞程度进行分析评价。结果 77例患者均能清晰显示肿瘤外周边缘及肿瘤实质的栓塞情况。13例化疗栓塞前作C臂CT检查者,除显示与CT所见相同外,尚有3例显示出肝内微小瘤灶。结论 C臂CT技术是继常规CT之后,因血管内介入检查中需要观察层面图像,评价治疗效果、制订手术方案而采用的一种高新技术。C臂CT服务于DSA诊疗现场,便于制订手术方案。相比于常规CT平扫能提供更直观、更丰富、更准确的信息。可用于多系统介入治疗。
Objective To discuss the application of C-arm CT scanning technology in performing transcatheter arterial chemoembolization for hepatic cancer.Methods Seventy-seven patients of hepatic cancer were treated with selective transcatheter arterial chemoembolization（TACE）,which was followed by C-arm CT scanning to observe the embolization effect.C-arm CT scanning was also performed before TACE in 13 cases.Three-dimension reconstruction of the images was carried out on Integris 3D-RA workstation.The therapeutic results were evaluated.Results The embolization state of both the peripheral margin and the body of the tumor could be clearly displayed on CT scans in all 77 patients.Some tiny liver lesions were also detected in 3cases.Conclusion C-arm CT scanning technology is a newly-developed high-tech examination.This examination is very helpful for making the proper operation scheme and for evaluating the curative effect of intravascular intervention.Compared to the traditional CT scanning,C-arm CT scanning can provide more accurate information and stereoscopic image of the lesions,therefore,the whole course of the interventional procedure can be entirely under the operator＇s control and the curative effect can be evaluated at any time during the operation.C-arm CT scanning can be effectively employed in interventional therapy for multisystemic disorders.
