摘　　要：目的探讨超声对乳腺导管原位癌(ductal carcinoma in situ,DCIS)的诊断价值。方法收集经手术病理确诊的导管原位癌患者33例,比较不同级别导管原位癌的超声表现及诊断符合率。结果高级别DCIS 13例,低-中级别DCIS 20例,术前超声提示可能恶性24例,超声对DCIS、高级别DCIS、低中级别DCIS诊断的符合率分别为72.7%、92.3%、60.0%。超声对高级别DCIS与低中级别DCIS的诊断敏感性差异有统计学意义(P=0.042)。低回声、形态不规则、微钙化是DCIS的超声表现的重要特征。结论超声对直径≥5mm的导管原位癌有很好的诊断价值,对高级别DCIS比低-中级别DCIS有更好的诊断价值。Objective To evaluate the diagnosis value of ultrasound （US）, in breast ductal carcinoma in si tu. Methods All recorded 33 cases of breast ductal carcinoma in situ（DCIS） in women from the Socond People＇s of Shenzhen were included. The accuracy rate and the US features of different grade DCIS were compared. Results There were 13 cases of high-grade DCIS and 20 cases low-intermediate-grade DCIS. Ultrasound indicated 24 possible malignant tumors. The accuracy rate of US of DCIS, high grade DCIS, low-intermediate-grade DCIS were 72.7%, 92.3% and 60.0 %, respectively. The differentiation diagnosis between high-grade DCIS and low-intermediate-grade DCIS was statistically significant（P= 0. 042）. The important features of DCIS were hypoechoic,irregular in shape and a bit calcific on the US images. Conclusions US is of excellent diagnostic value in DCIS≥5 mm in diameter. US is of greater value in high-DCIS than in low-intermediate-grade DCIS.
