乳腺导管内癌超声图像特征分析

Feature analyses breast ductal carcinoma in situ by ultrasound

目的分析乳腺导管内癌的声像图特征及利用乳腺影像报告数据系统-超声版(BI-RADS-US)进行最终评估,探讨超声对该病的诊断价值。方法回顾性分析并总结2007年1月至2010年1月期间我院经手术病理证实的59例乳腺导管内癌的声像图特征,并依照BI-RADS-US进行最终评估。结果根据乳腺导管内癌的声像图特征,可分为5大类:(1)结节肿块型;(2)导管扩张填充型;(3)结构紊乱型;(4)囊实性混合回声型;(5)无占位的单纯钙化点型。利用BI-RADS-US评估乳腺导管内癌,得到超声诊断符合率为77.9%。结论高频超声在乳腺导管内癌的诊断过程中发挥着重要作用。

Objective To analyze the ultrasound features of ductal carcinoma in situ（DCIS） and breast imaging reporting and data system（BI-RADS-US） assessment.Methods The sonographic characteristics in 59 cases of pathologically-confirmed DCIS from January,2007 to January,2010 were retrospectively analyzed and assessed by BI-RADS-US.Results According to the sonographic characteristics of DCIS,all the sonograms were classified into 5 categories：（1） node or similar issue;（2） ductal ectasia filled with stuff;（3） architecture disorder;（4） mass with both anechoic and echogenic components;（5） calcification only.All the cases were assessed by BI-RADS-US and the coincidence rate of ultrasound of DCIS was 77.9%.Conclusion High-frequency ultrasound is important for diagnosis of DCIS.
