摘要
目的探讨小剂量预实验法与对比剂追踪智能触发技术在螺旋CT肝动脉成像中的应用价值。方法 87例原发性肝癌患者,随机分为两组,A组42例采用小剂量预实验法,B组45例采用对比剂追踪智能触发技术,对两种方法所获得的肝动脉CTA图像质量进行评价,并测量肝动脉1～4级分支增强后的CT值,进行统计学分析。结果 B组图像质量优于A组,两者差异有统计学意义(P<0.05);两组肝动脉1～2级分支增强后CT值比较差异无统计学意义(P>0.05);B组3级、4级分支增强后的CT值高于A组,差异有统计学意义(P<0.05)。结论采用对比剂追踪智能触发技术进行肝动脉CTA检查,简化了操作程序,而且图像质量优良。
Objective To compare the clinical value of low dose pretest technique with automatic bolus tracking technique in multi-slice CT angiography of hepatic artery.Methods Eighty-seven patients with primary liver cancer were divided into two groups randomly,42 patients（group A）were treated with low dose pretest technique,and the other 45 patients（group B）were treated with automatic bolus tracking technique.The quality of CT angiography image were evaluated,the densities of the first to fourth hepatic artery branches were measured and the results were analyzed.Results The images quality of group B was better than that of group A,the difference was significant（P0.05）.There was no significant statistical difference in the density of the first and secondary hepatic artery branches between the two groups（P0.05）,but the difference of the density of the third hepatic artery branches was significant between the two groups（P0.05）.Conclusion Automatic bolus tracking technique is feasible in CTA of hepatic artery,which can improve image quality and simplifying procedures.
