摘　　要：目的:通过和普通全数字乳腺摄影(FFDM)做对比,探讨数字乳腺断层融合摄影(DBT)对乳腺导管原位癌(DCIS)的诊断价值和临床应用。方法:回顾分析我院2018年3月至2020年2月经手术病理证实的110例乳腺导管原位癌(DCIS)的FFDM和DBT的影像表现特点并与病理对比研究。结果:110例DCIS的数字乳腺断层融合摄影(DBT)和普通全数字乳腺摄影(FFDM)的影像学特征做对比:结构扭曲伴或不伴钙化增加12例,非对称致密伴或不伴钙化显示增加10例,结节或肿块显示增加8例,形态不规则、边界不清显示增加12例。DBT对乳腺导管原位癌(DCIS)的检出率和诊断符合率均高于FFDM(检出率96.3%vs 87.3%,χ^(2)=6.051,P<0.05;诊断符合率80.0%vs 53.6%,χ^(2)=17.245,P<0.05),二者差异具有统计学意义。结论:数字乳腺断层融合摄影(DBT)能够更佳显示DCIS的影像特征,有助于提高诊断准确率,作为乳腺摄影的新技术,临床可根据实际需要广泛应用。Objective:To discuss the value of clinical application of digital breast tomosynthesis(DBT)compared with full-field digital mammography(FFDM)in ductal carcinoma in situ(DCIS).Methods:We retrospectively studied the full-field digital mammography and digital breast tomosynthesis performance characteristic of 110 cases which had been proved to be ductal carcinoma in situ(DCIS)by surgery pathology from March 2018 to February 2020 in our hospital.Compared analysis was made between the imaging features and the pathology.Results:AS for the imaging features of digital breast tomosynthesis(DBT)of 110 cases of ductal carcinoma in situ(DCIS),compared with full-field digital mammography(FFDM):12 more cases presented structural distortion with or without calcification,10 more cases presented asymmetric density with or without calcification,8 more cases presented nodules and masses,12 more cases presented irregular shape and boundary.The detection rate and compliance rate of DBT in ductal carcinoma in situ were significantly higher than that of FFDM(detection rate 96.3%vs 87.3%,χ^(2)=6.051,P<0.05;compliance rate 80.0%vs 53.6%,χ^(2)=17.245,P<0.05),and the difference was statistically significant.Conclusion:DBT can clearly display the imaging feature and improve diagnostic efficacy of ductal carcinoma in situ(DCIS),As a new mammography technology,it is secure and can be applied according to clinical needs.
