自动乳腺全容积成像和常规二维超声对非浸润性导管癌的诊断价值对比研究

目的比较自动乳腺全容积成像（ABVS）和常规二维超声对非浸润性导管癌[包括导管原位癌（DCIS）或DCIS伴微浸润]的诊断价值。方法回顾比较经病理确诊为DCIS或DCIS伴微浸润的42个病灶，分析ABVS和常规二维超声声像图特点。结果ABVS和常规二维超声的病灶检出率分别为95.24％、90.48％，统计学无显著意义（P〉0.05）；定性诊断准确率分别为87.50％、71.05％，具有统计学差异（P〈0.05）。结论ABVS对非浸润性导管癌的诊断较常规二维超声有一定优势。

Comparison between automated breast volume scanning and conventional two-dimensional ultrasound in the diagnosis of non-invasive ductal carcinoma

Objective To compare automated breast volume scanning （ABVS）and conventional 2D breast ultrasound （US）in the diagnosis of non-invasive ductal carcinomas. Methods 42 patients with pathologically confirmed ductal carcinoma in situ （DCIS） or DCIS with micro-invasion underwent ABVS and conventional 2D US. The sonographic characteristics were analyzed retrospectively. Results The lesion detection rate of ABVS （95.24%） was not significantly （P 〉 0.05） higher than that of 2D US （90.48%） whereas the diagnostic accuracy rate of ABVS （87.50%） was significantly higher （P 〈 0.05） than that of 2D US （71.05%）. Conclusions ABVS has higher accuracy than conventional 2D US in the diagnosis of non-invasive ductal carcinoma.
