目的 探讨透视触发造影剂团追踪 (FTB)技术在小肝癌 (SHCC)多期扫描中的临床应用价值。方法 2 0例临床及其它检查诊断或可疑小肝癌的患者。分成 2组 ,对照组 1 0例按常规方法进行增强扫描 ,实验组 1 0例增强扫描前采用FTB技术 ,监测出主动脉及心脏内造影剂浓度从无到有的变化过程图后 ,再接着进行增强扫描。结果 对照组仅 3例获得较好动脉期 ,确诊小肝癌 3例 ;实验组所有病例均获得最佳动脉期 ,检出小肝癌 7例 ,1 0例确诊的小肝癌均得到手术及病理的证实。结论 FTB技术的应用可提高小肝癌的检出率
Objective To investigate the clinical value of fluoroscopy-triggered contrast media group tracking (FTB) in multi-phase small-cell carcinoma of the liver (SHCC). Method 20 cases of clinical and other diagnostic tests or suspected small liver cancer patients. Were divided into two groups, the control group of 10 patients underwent enhanced scanning by conventional methods, the experimental group 10 cases of enhanced scanning before using FTB technology to monitor the aortic and cardiac contrast agent concentration change from scratch process map, and then Perform enhanced scan. Results In control group, only 3 cases got better arterial phase, and 3 cases of small hepatocellular carcinoma were diagnosed. All cases in experimental group got the best arterial phase, 7 cases of small hepatocellular carcinoma were detected, and 10 cases of confirmed small hepatocellular carcinoma were confirmed by operation and pathology . Conclusion The application of FTB technology can improve the detection rate of small liver cancer
