目的：分析彩色多普勒超声（ CDU）与X线钼靶联合应用于乳腺癌诊断的价值。方法对98例乳腺肿瘤患者的CDU与X线钼靶摄片的诊断及鉴别诊断结果进行回顾性分析和比较。结果98例患者中71例病理证实乳腺癌。联合诊断的符合率与单独应用CDU、X线钼靶相比，差异均有统计学意义（χ2值分别为5．87和13．14，均P＜0．05）。联合诊断乳腺癌的准确率为91．5％，高于单独应用X线钼靶、CDU诊断乳腺癌的准确率分别为76．1％和77．5％，差异有统计学意义（χ2值分别为6．27和5．38，均P＜0．05）。直径＜1．0cm的肿块，联合诊断的准确率高于单用CDU、X线钼靶（χ2值分别为3．11和5．60，均P＜0．05）。结论 CUD检查和X线钼靶摄片检查各具优势，联合应用能明显提高乳腺癌的检出率。%Objective To investigate the value of color Doppler ultrasonograph ( CDU) combined with mammography in diagnosis of breast cancer.Methods The results of CDU and mammography for 98 patients with breast tumor were analyzed retrospectively , and they were compared with final obtained surgical-pathological examinations .Results The surgical-pathologic examinations confirmed breast cancer in 71 of 98 breast tumor patients .The diagnostic coincident rate of CDU combined with mammography was significantly higher than that of CDU or mammography (χ2 value was 5.87 and 13.14, respectively, both P<0.05).The diagnostic accuracy rate of CDU combined with mammography was 91.5%, which was significantly higher than of CDU (77.5%) or mammography (76.1%) (χ2 value was 6.27 and 5.38, respectively, both P<0.05).The accuracy rate of CDU combined with mammography was significantly higher than that of CDU or mammography in detecting small cancer (diameter<1.0cm) (χ2 value was 3.11 and 5.60, respectively, both P<0.05).Conclusion CUD and mammography examination have their own advantages .Combining CDU with mammography can improve the detection rate of breast cancer significantly .
