目的 探讨彩色多普勒超声在大肠癌诊断中的应用价值。方法 总结48例经手术及病理证实的大肠癌彩色多普勒超声声像图表现、血流特点以及与Dukes’分期的关系。结果 大肠癌的彩色多普勒超声特征性表现为“假肾征”“靶环征”,83.3％(40/48)可于病灶内及周边部检测到较丰富的血流信号,其平均血流速度为16.24±0.05Cm/s,阻力指数为0.69±0.01,为高速、高阻血流特点。结论 彩色多普勒超声在大肠癌诊断中有着重要的应用价值。
Objective To explore the value of color Doppler ultrasound in the diagnosis of colorectal cancer. Methods The color Doppler echocardiography, blood flow characteristics and the relationship with Dukes’ stage in colorectal cancer of 48 cases confirmed by operation and pathology were summarized. Results Color Doppler echocardiography of colorectal cancer was characterized by “pseudo-kidney sign” and “target ring sign”. 83.3% (40/48) of the patients showed more abundant blood flow signals in the lesion and the periphery, and the mean blood The flow velocity was 16.24 ± 0.05Cm / s, and the resistance index was 0.69 ± 0.01, which was the characteristic of high-speed and high-resistance blood flow. Conclusion Color Doppler ultrasound in the diagnosis of colorectal cancer has an important value.
