研究自动乳房全容积成像（ABVS）冠状面的边缘特征对于诊断女性乳腺实性肿瘤的价值。

回顾性分析206例女性乳腺肿块患者（230个结节）的术前手持式超声（HHUS）和ABVS资料，HHUS主要观察肿块的边缘、形态、生长方位、内部回声、有无钙化、后方回声特征及肿块的相关特征、彩色血流及多普勒频谱特征。采用SPSS 20.0软件统计分析，计量资料采用（±s）表示，敏感性和特异性的比较采用配对卡方检验。一致性检验采用Kappa检验。

HHUS的边缘恶性特征、HHUS的所有特征、ABVS冠状面的边缘恶性特征以及ABVS的边缘恶性特征联合HHUS的所有特征诊断乳腺实性肿瘤的敏感性分别为62.40%、71.40%、72.93%、88.72%；特异性分别为80.41%、76.29%、77.32%、75.26%。ABVS冠状面的边缘恶性特征诊断乳腺实性肿瘤的敏感性高于HHUS的边缘恶性特征，两者差异有统计学意义（P < 0.001），一致性检验Kappa = 0.762；ABVS冠状面的边缘恶性特征结合HHUS的所有特征诊断乳腺实性肿瘤的敏感性高于单纯HHUS，两者的差异有统计学意义（P = 0.001），一致性检验Kappa = 0.778。

ABVS冠状面可以提供更多的乳腺肿瘤边缘特征，联合HHUS有助于提高诊断女性乳腺恶性肿瘤的敏感性。

To investigate the value of margin features in the coronal plane of automated breast volume scanner (ABVS) for the diagnosis of solid breast tumors in women.

The preoperative data on handheld ultrasound (HHUS) and ABVS of 206 female breast mass patients with 230 nodes were retrospectively analyzed. HHUS focused on the margins, morphology, growth orientation, calcification, internal echogenic features, posterior echogenic features, color blood flow and Doppler spectrum features of the mass. SPSS 20.0 software was used for statistical analysis, ±s used for the mean of quantitative data, paired chi-square test was used for comparison of sensitivity and specificity. Kappa test was used for consistency testing.

The sensitivities of the malignant marginal features of HHUS, all features of HHUS, the malignant marginal features of ABVS coronal plane, and the malignant marginal features of ABVS combined with all features of HHUS for the diagnosis of solid breast tumors were 62.40%, 71.40%, 72.93%, and 88.72%, respectively, the specificities were 80.41%, 76.29%, 77.32%, and 75.26%, respectively. The sensitivity of the malignant marginal features of the ABVS coronal plane was higher than that of the HHUS, the difference had statistics significance (P < 0.001), the Kappa was 0.762 in the consistency test. The sensitivity of the malignant marginal features of the ABVS coronal plane combined with all features of the HHUS was higher than that of the HHUS alone in the diagnosis of solid breast tumors, the difference had statistics significance (P = 0.001), the Kappa was 0.778 in the consistency test.

ABVS coronal plane can provide more marginal features of breast tumors. The sensitivity of diagnosing malignant tumors of female breast will be improved when combined with HHUS.
