Abstract: Objective To evaluate the diagnostic value of breast ultrasound, mammography, and MRI for breast ductal carcinoma in situ. Methods Forty cases of breast ductal carcinoma in situ treated in our hospital from June 2015 to June 2018 were retrospectively collected. All 40 patients were examined by ultrasonography, mammography and MRI if necessary. The detection rates of three kinds of image diagnosis methods were observed. Results A total of 36 cases of breast ductal carcinoma in situ were detected by ultrasonography, with the detection rate of 90.00% (36/40); 13 cases of breast ductal carcinoma in situ were detected by mammography, with the detection rate of 61.90% (13/21); 14 cases of breast ductal carcinoma in situ were detected by MRI, with the detection rate of 93.33% (14/15); the difference was statistically significant (P=0.011). When combined the three, the positive rate of diagnosis of breast ductal carcinoma in situ reached to 100.00% (40/40). Conclusion The sensitivity of ultrasonography and mammography in the diagnosis of breast ductal carcinoma in situ is general. The combined application of ultrasound, mammography, and MRI has a high detection rate of breast ductal carcinoma in situ.

摘要： 目的 探究超声、钼靶X线摄影与MRI对乳腺导管内原位癌的临床诊断价值。方法 回顾性收集2015年6月至2018年6月在本院行乳腺导管内原位癌治疗的40例患者,全部患者均采用超声检查,必要时行乳腺钼靶及MRI检查,观察3种影像诊断的检出率。结果 由超声检出乳腺导管内原位癌36例(36/40),检出率为90.00%;钼靶检出导管内原位癌13例(13/21),检出率为61.90%;MRI检出导管内原位癌14例(14/15),检出率为93.33%;差异有统计学意义(P=0.011)。三者联合使用时,对导管内原位癌的诊断阳性率可达到100.00%(40/40)。结论 超声及钼靶对导管内原位癌诊断的敏感性一般,通过超声、钼靶X线摄影与MRI联合应用,对乳腺导管内原位癌具有较高的检出率。
