[目的]比较X线钼靶、高频彩超对早期乳腺癌诊断的优缺点,探讨二者联合应用的诊断价值。[方法]选择术前有超声和X线钼靶检查,并经过病理组织学证实的45例早期乳腺癌病例,对其影像资料进行回顾性分析。[结果]超声明确诊断符合率73.3%(33/45),钼靶摄影诊断符合率86.7%(39/45),两者联合应用诊断符合率95.6%(43/45)。超声检出肿块43例(95.6%):其中单纯肿块33.3%(15/45),肿块伴钙化44.4%(20/45),肿块伴蟹足征28.9%(13/45),肿块后方回声衰减22.2%(10/45);彩色多谱勒(CDFI)示38例(84.4%)显示数量不等的血流信号:14例(31.1%)显示星点状少量血流信号,24例(53.3%)显示较丰富血流信号,多为穿入性高阻力动脉血流。钼靶检出肿块32例(71.1%),肿块毛刺征24例(63.3%),钙化征28例(62.2%),其中单纯钙化6例,肿块伴钙化22例。[结论]超声与钼靶对乳腺癌诊断均有较大价值,二者各有优势互补,联合应用可以提高早期乳腺癌诊断的符合率。 [Objective] To compare the advantages and disadvantages of mammography and high-frequency color Doppler ultrasonography in the diagnosis of early breast cancer and to explore the diagnostic value of the combination of them. [Methods] The 45 cases of early breast cancer confirmed by pathology and histology before operation were examined by ultrasound and X-ray mammography. The imaging data were retrospectively analyzed. [Results] The coincidence rate of 73.3% (33/45) confirmed by ultrasonography and 86.7% (39/45) by mammography respectively. The diagnostic coincidence rate was 95.6% (43/45). 43 cases (95.6%) were detected by ultrasound, of which 33.3% (15/45) were simple mass, 44.4% (20/45) mass calcified with calcification, 28.9% 38 (84.4%) showed a small number of blood flow signals in 14 cases (31.1%), 24 cases (53.3%) showed colorimetric Doppler results in 22.2% (10/45) %) Showed more abundant blood flow signals, mostly penetrating high resistance artery blood flow. There were 32 cases (71.1%) of the tumor detected by molybdenum target, 24 cases (63.3%) of gross burr sign and 28 cases (62.2%) of calcification sign, including simple calcification in 6 cases and mass with calcification in 22 cases. [Conclusion] Ultrasound and mammography are of great value in the diagnosis of breast cancer, both of which have their own advantages and complement each other. Combined application can improve the coincidence rate of diagnosis of early breast cancer.
