摘要
目的：探讨超声弹性成像对常规超声发现的可疑恶性乳腺实性小肿块（直径≤20mm）的鉴别诊断价值。材料和方法：对85例乳腺单发实性小肿块患者先行灰阶超声、彩色和能量多普勒超声检查，再行实时超声弹性成像检查。弹性成像采用改良5分法进行评价，将超声诊断结果与病理结果进行对照。结果：以弹性评分4-5分为恶性预测标准，其诊断乳腺小肿块良、恶性的敏感性、特异性和准确性分别为89．18％、89．58％、89．41％，灰阶超声、彩色和能量多普勒超声联合诊断乳腺小肿块良、恶性的敏感性、特异性和准确性分别为48．65％、79．16％、65．88％。X^2。检验，两者准确性差异有统计学意义（X^2=13．557，P〈O．001）。结论：超声弹性成像有助于对常规超声发现的可疑恶性乳腺实性小肿块进行更好的诊断和鉴别。
Objective： To assess the diagnostic value of uhrasonographic elastography for identifying suspected malignant breast neoplasms. Materials and Methods： Eighty five patients with small single solid breast neoplasms first underwent two dimensional, color Doppler and power Doppler ultrasound. Then elastography was performed, and used an improved 5 point system to diagnose malignant or benign lesions. The ultrasonographic results were compared with pathologic findings. Results： Taking the elasticity score 4-5 as malignant standard, the diagnostic sensitivity was 89.18%, specificity was 89.58%, accuracy was 89.41%. The combined diagnostic sensitivity of two-dimensional, color Doppler and power Doppler ultrasound was 48.65%, specificity was 79.16%, accuracy was 65.88%. Conclusion： Real time ultrasound elastography is a promising imaging tech- nique that can assist in the differential diagnosis of malignant small single solid breast neoplasm.
