高频彩超对乳腺小结节的诊断价值

The Value of High Frequence Color Doppler Ultrasonography(HFCDU) in Diagnosis of Small Breast Nodules

目的探讨高频彩超对乳腺小结节的诊断价值。方法对37例乳腺小结节进行高频彩色多普勒超声检查,并将其超声图像与术后病理结果进行回顾性分析。结果彩色多普勒超声对良恶性结节的诊断符合率分别为93.3%、85.7%。良性结节多表现为外形规则、边界清晰、内部回声均匀、后方回声无衰减,彩色多普勒血流分级多为0～Ⅰ级,阻力指数RI<0.7;而恶性结节多表现为外形欠规则、边界不清、毛刺征、内部回欠均匀、微钙化,后方可有衰减,彩色多普勒血流分级多为Ⅱ～III级,RI>0.7。结论高频彩超对乳腺小结节具有重要诊断价值。

Objective To study the value of high frequence Color Doppler Ultrasonography in diagnosis of small breast nodules. Methods Thirty seven cases with small breast nodules underwent the examinations of high frequence color Doppler ultralsound.And the ultralsonic imaging of 37 small breast nodules were retrospectively analyzed and compared with postoperative pathology.Results Diagnostic rates of HFCDU in benign and malignancy nodules of breast were 93.3% and 85.7%.The benign nodules usually appeared as regular shape,smooth border,homogeneous interal echoes,CDFI grades 0-I,RI0.70;Otherwise,The malignancy nodules often appeared as irregular shape,obscure border,sentus,uneven echoes,microcalcification and rear attenuation,CDFI grades were II-III and RI0.7.Conclusion HFCDU has significant clinical value in diagnosis of small breast nodules.
