高频超声结合彩色多普勒血流显像诊断乳腺肿块171例分析

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。

High-frequency ultrasonography and color Doppler flow imaging in diagnosis of breast tumor:a report of 171 cases

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....
