| 目的 评价多普勒超声对乳腺肿块鉴别诊断的临床应用价值。 方法 60例女性患者,术前分别进行二维超声、彩色多普勒超声和能量多普勒超声检查。 结果 根据肿块的二维超声图像特征边缘轮廓、包膜、侧方声影、内部回声、后壁回声、肿物后回声、组织浸润及纵横比鉴别诊断乳腺肿块的敏感度为96.7%,特异度为60%,准确度为78.3%。二维超声联合CDFI血流信号分级(恶性Ⅱ~Ⅲ级,良性0~Ⅰ级),RI≥0.7,PI≥1.1 及PDI分型(恶性Ⅲ~Ⅳ型,良性Ⅰ~Ⅱ型),CPD≥21%鉴别诊断乳腺肿块的敏感度为93.3%,特异度为83.3%,准确度为88.4%。二者比较,特异度有显著性差异(P<0.02),敏感度和准确度无显著性差异(P>0.05)。 结论 在二维超声的基础上联合CDFI和PDI鉴别诊断乳腺肿块,明显提高了诊断恶性乳腺肿块的正确率,有很大的临床应用价值。 |

| Objective To evaluate the clinical value of Doppler ultrasound in differentiation of breast neoplasms. Methods Sixty consecutive patients with breast neoplasms were prospectively assessed by two-dimensional ultrasound, color Doppler ultrasound and power Doppler ultrasound before operation. All were proved by pathology. Results Based on the two-dimensional ultrasound features the differential diagnosis sensitivity, specificity and accuracy for the breast neoplasms were 96.7%, 60% and 78.3% respectively. Based on the color Doppler signal scores and RI≥0.7 or/and PI≥1.1, the differential diagnosis sensitivity, specificity and accuracy were 86.7%, 70% and 78.3% respectively. Based on the power Doppler signal types and CPD≥21%,the differential diagnosis sensitivity, specificity and accuracy were 86.7%, 76.7% and 81.6% respectively. Integrating with the three methods, the differential diagnosis sensitivity, specificity and accuracy were 93.3%, 83.3% and 88.4%. Conclusion In this study, two-dimensional ultrasound integrating with color Doppler ultrasound and power Doppler ultrasound can differently diagnose the breast neoplasm. |
