目的 :探讨腔内彩色多普勒超声对直肠癌诊断的价值。方法 :分析了经腔内彩色多普勒超声诊断并经手术或病理证实的 33例直肠癌的彩色多普勒血流特征。结果 :33例直肠癌无论是浸润肌层及肠外脂肪组织 ,均能显示以动脉为主的彩色多普勒血流信号 ,且血流丰富。结论 :彩色多普勒超声对直肠癌的敏感性高 ,提高了对直肠癌浸润肠壁深度及周围脏器诊断的准确率 ,为临床是否手术提供有价值的信息
Objective: To investigate the value of intracavitary color Doppler ultrasound in the diagnosis of rectal cancer. Methods: Color Doppler flow characteristics of 33 cases of rectal cancer diagnosed by endoscopic color Doppler ultrasonography and surgically or pathologically were analyzed. Results: 33 cases of rectal cancer, both infiltrating myometrial and extra-intestinal adipose tissue, showed arterial-based color Doppler flow signals, and the blood flow was rich. Conclusion: Color Doppler ultrasound is highly sensitive to rectal cancer, which improves the accuracy of the depth of rectal cancer infiltration of intestinal wall and the diagnosis of peripheral organs, and provides valuable information for clinical operation
