目的:探讨高频超声诊断仪结合彩色多普勒血流显像(CDFI)诊断乳腺良、恶性肿瘤的价值.方法:应用高频彩色多普勒超声诊断仪检查171例乳腺肿瘤患者的一般情况,再采用CDFI检测肿瘤周边及内部的血管分布,并用频谱多普勒测量血流的峰值流速、阻力指数、搏动指数等参数,同时探查双侧腋窝有否肿大淋巴结.将超声检查结果与术后病理检查结果进行比较.结果:术后病理诊断乳腺良、恶性肿瘤分别为82例和89例,而超声直接诊断或提示诊断为良、恶性分别为71例和85例,符合率分别为95.5%和86.6%.良性组中性质待定5例,误诊为恶性6例,误诊率为7.3%;恶性组中误诊4例,误诊率为4.5%.CDFI显示乳腺良、恶性肿块在边界、形态、内部回声、侧方声影、后方回声、血管分布、血流动力学参数等方面差异均有统计学意义(P<0.01).结论:高频超声结合CDFI可对肿块的大小、数目、位置等一般情况能作出准确判断,CDFI能评价肿块的二维图像、血流动力学参数,对提高良、恶性乳腺肿块的诊断正确率有较高价值.%Objective:To explore the value of high frequency ultrasonography (HFU)and color Doppler flow imaging (CDFI) in diagnozing the breast tumor. Methods:A total of 171 patients were diagnosed by HFU and CDFI. Two-dimensional ultrasound was used to observe the size,margin and blood vessel distribution of the tumor;color Doppler was adopted to measure the degree of the blood flow signal,the peak systolic velocity and the resistance index. The results were compared with those by pathological examination after operation. Results:Compared with the pathological results, the accuracy of preoperative HFU reached 95.5 ％ (71/82 benign and 85/89 malignant)in diagnosing the breast tumor. The misdiagnosis rate was 7.3％ (6/82) and 4.5％ (4/82)in the benign and malignant breast tumor,respectively. Benign and malignant tumors had evident discrepancy at the border, shape, internal echo, side echo, rear echo,blood vessel distribution and hemodynamics (P ＜ 0. 01 ). Conclusions: HFU and CDFI can determine the size, number and location of the breast tumor. CDFI may evaluate the 2D images and hemodynamics parameters, which are of great value in making correct diagnosis of benign or malignant breast tumors.
