| 目的 本文设计一种新彩色多普勒影像处理方法以突出展现肝细胞癌(HCC) 的异常涡流。方法 计算
两项新(双- 向,低峰) 指数检测HCC 特征血流。结果 在实验资料,由狭窄形成的涡流其两项指数较高。在临床方
向,HCC 的两项指数显著高于慢性肝病患者门脉及肝静脉内的相应测值。77 % HCC 患者可检出该涡流,而很少见
于门脉或肝静脉。结论 该项新技术可用来区别HCC 涡流。 |
| 英文摘要: |
| Purpose This paper designed a new color Doppler imaging technique that detects and emphasizes turbulence ,
which is a characteristic of blood flow in hepatocellular carcinoma (HCC) . Methods Two indices that determine a characteristic tumor flow ,the bi-directional and low-peak indices ,were computerized. Results In phantom study ,both indices of
turbulence caused by stenosis were much higher. In the clinical study ,both indices were significantly higher in tumors than
in the portal vein or hepatic vein. A turbulence blood flow was detected in 77 % of HCC ,whereas such detection seldom occured in the portal or hepatic vein. Conclusion This new technique has the potential to distinguish turbulence in HCC. |
