结直肠癌发病率逐年增高是世界性趋势。本病的超声诊断简便易行,近年研发的新仪器、新技术,特别是EUS、彩超多普勒血流显像技术对肠壁层次结构的检查显示更加清晰,对肿瘤血管的检测分期和血流波型分析开辟了癌瘤病理生理学分期及病理组织学分类的依据,均已成为临床上必要的信息。本文就结直肠癌的声像诊断、分型、癌瘤侵袭深度与分期、肿瘤血管血流波型分析及鉴别诊断等方面进行综述。
The increasing incidence of colorectal cancer is a worldwide trend. Ultrasound diagnosis of the disease is simple and easy to implement, in recent years, the development of new instruments, new technologies, especially EUS, Doppler color Doppler flow imaging of the hierarchy of the intestinal wall examination showed more clearly on tumor blood vessels staging and blood Flow-wave analysis opens up the basis for the classification of histopathological staging and histopathology of cancer, and has become clinically necessary information. This article reviews the diagnosis and classification of colorectal cancer by acoustic imaging, the depth and stage of invasion of cancer, the analysis of tumor blood flow waveform and differential diagnosis.
