目的 探讨二维及彩色多普勒超声诊断良恶性结肠肿瘤的价值。方法 6 2例结肠肿瘤患者共有肿块 82个 ,对肿块超声成像特征进行分析。结果 82个肿块中经超声诊断为恶性者 74个 ,其中有 6 9个经手术及纤维结肠镜活检后病理证实 (符合率 93.2 4 % )。结肠恶性肿瘤的特征性声像图为“假肾”征、“靶环”征及隆起包块等 ;良恶性肿瘤的彩色多普勒血流显像 (color Doppler flow image,CDFI)显示率及阻力指数 (resistant index,RI)存在显著差异。结论 超声在鉴别结肠良恶性肿瘤中有较高的价值
Objective To investigate the value of two-dimensional and color Doppler ultrasound in the diagnosis of benign and malignant colon tumors. Methods Sixty two patients with colorectal cancer had a total of 82 lumps, and the characteristics of lump ultrasound imaging were analyzed. Results Totally 74 of 82 masses were ultrasonographically diagnosed as malignant. Among them, 69 were pathologically confirmed by operation and colonoscopy (93.2 4%). The characteristic radiographs of colon malignant tumors were “fake kidney” sign, “target ring” signs and bulging masses, etc. The rates of color Doppler flow imaging (CDFI) in benign and malignant tumors and There was a significant difference in resistance index (RI). Conclusion Ultrasound in the identification of benign and malignant colon tumors have a higher value
