高频彩色多普勒超声在鉴别乳腺良恶性肿块中的应用

目的探讨高频彩色多普勒超声在鉴别乳腺良恶性肿块中的应用价值。方法回顾性分析经病理证实的乳腺良性肿块108例(良性组)和恶性肿瘤72例(恶性组)患者的高频彩色多普勒超声检查声像图特征,并与病理诊断结果进行对比。结果乳腺恶性肿瘤高频彩色多普勒超声诊断与病理诊断符合率为94.4%。乳腺良性肿块表现为境界清晰,形态规则,内部回声均匀,周边可见包膜;恶性肿块多表现为边界不清楚,形态不规则,边缘粗糙呈毛刺蟹足状,周边无包膜内部回声不均,后方回声衰减,边缘有不规则的强回声晕。恶性组血流分级程度高于良性组(P<0.05);良性组Vmax及RI范围小于恶性组(P<0.05)。结论高频彩色多普勒超声在乳腺肿块良恶性诊断中具有重要的临床价值。

The application of high frequency color Doppler ultrasonography on identification of benign and malignant breast lump

Objective To evaluate the clinical value of high frequency color Doppler ultrasonography on identification of benign and malignant breast lump.Methods Retrospective analysis of pathologically confirmed 108 cases of benign breast lump（benign group） and cancer of 72 cases patients of color Doppler ultrasound imaging features（malignant group）,and compared pathological diagnosis result.Results The overall conformity rate of sonographic decisions and pathological results was 94.4%.The shape of benign breast lumps was regular,the boundary was smooth and tidy,had capsule;Malignant breast lump showed more irregular borders,edges rough,no capsule,the internal echo uneven,posterior echo attenuation,irregular hyperechoic edge halo.Blood flow grade level of malignant group was higher than that of benign group（P0.05）;Vmax and RI range of benign group were less than those of malignant group（P0.05）.Conclusion High frequency color Doppler ultrasonography has high value in the diagnosis of breast lump.
