目的 分析乳腺良恶性肿瘤的二维及彩色多普勒超声表现,评价彩色多普勒超声在诊断乳腺癌中的应用价值.方法 对674例乳腺肿瘤患者(恶性327例,良性347例)进行二维超声及彩色多普勒超声检查,以二维超声观察肿块的大小、形态、边界、内部回声等,以彩色多普勒超声观察肿块内部血流信号,测量血流峰值速度(PSV)和阻力指数(RI)等.结果 674例中超声发现肿块671例,肿块大小0.50 cm×0.41 cm～5.42 cm×4.10 cm.恶性肿瘤肿块纵横径比≥1.0占69.11%(226/327),肿块边界不整齐,呈"锯齿"状或"蟹足"状约占81.35%(266/327),肿块内部沙粒样钙化点占61.47%(201/327);彩色多普勒对血流信号的显示率为92.97%(304/327),PSV为15.34～39.76 cm/s,RI为0.65～0.98,RI≥0.70占91.61%(262/286).良、恶性肿瘤在肿块纵横径比、肿块边界、沙粒样钙化及血流信号、PSV、RI等方面差异均有统计学意义(P＜0.01).结论 二维超声结合血流信号、PSV及RI值可显著提高乳腺良、恶性肿瘤的诊断与鉴别,彩色多普勒超声在乳腺癌的诊断中具有重要作用.
目的 分析乳腺良噁性腫瘤的二維及綵色多普勒超聲錶現,評價綵色多普勒超聲在診斷乳腺癌中的應用價值.方法 對674例乳腺腫瘤患者(噁性327例,良性347例)進行二維超聲及綵色多普勒超聲檢查,以二維超聲觀察腫塊的大小、形態、邊界、內部迴聲等,以綵色多普勒超聲觀察腫塊內部血流信號,測量血流峰值速度(PSV)和阻力指數(RI)等.結果 674例中超聲髮現腫塊671例,腫塊大小0.50 cm×0.41 cm～5.42 cm×4.10 cm.噁性腫瘤腫塊縱橫徑比≥1.0佔69.11%(226/327),腫塊邊界不整齊,呈"鋸齒"狀或"蟹足"狀約佔81.35%(266/327),腫塊內部沙粒樣鈣化點佔61.47%(201/327);綵色多普勒對血流信號的顯示率為92.97%(304/327),PSV為15.34～39.76 cm/s,RI為0.65～0.98,RI≥0.70佔91.61%(262/286).良、噁性腫瘤在腫塊縱橫徑比、腫塊邊界、沙粒樣鈣化及血流信號、PSV、RI等方麵差異均有統計學意義(P＜0.01).結論 二維超聲結閤血流信號、PSV及RI值可顯著提高乳腺良、噁性腫瘤的診斷與鑒彆,綵色多普勒超聲在乳腺癌的診斷中具有重要作用.

Objective To analyze the characteristics of benign and malignant breast tumors with 2D and color Doppler ultrasound, and to assess the value of color Doppler ultrasound in the diagnosis of breast cancer. Methods A total of 674 patients (327 malignant and 347 benign) of breast tumor underwent 2D and color Doppler ultrasonogarphy. Two-dimensional ultrasound was used to observe the size, form, margin and internal echo of the tumors;color Doppler was performed to observe the degree of blood flow signal in the tumor, and to measure peak systolic velocity (PSV) and resistance index (RI). Results Totally 671 patients were diagnosed with ultrasound. The size of the tumors were from 0.50 cm×0.41 cm to 5.42 cm×4.10 cm. The ratio of vertical and transverse diameter of 69.11% (226/327) of the malignant tumors ≥1.0. Most tumors (266/327, 81.35%) presented with irregular margin like "incised" or "feet of crab";61.47% (201/327) had microcalcification. Color Doppler found that 92.97% (304/327) of the tumors had blood flow signal;PSV was 15.34-39.76 cm/s, RI was 0.65-0.98, and 91.61% (262/286)≥0.70. Significant differences of the ratio of vertical and transverse diameter, the margin of the tumor, microcalcification and blood flow signal, PSV and RI (P＜0.01) were found between benign and malignant breast tumors. Conclusion The diagnosis and differential diagnosis of benign and malignant breast tumors can be significantly improved with comprehensive analysis of 2D ultrasound, blood flow signal, PSV and RI. Color Doppler ultrasound plays an important role in the diagnosis of breast cancer.
