| 目的 比较自动乳腺全容积超声成像（ABUS）技术与常规超声对乳腺癌的诊断价值。
方法 回顾性分析126例乳腺肿块患者（132个结节）的术前常规超声和ABUS检查资料，分析总结其常规超声和ABUS冠状切面图像特征，以病理结果为金标准，计算并比较单独ABUS、常规超声及两者联合对乳腺结节的诊断效能。
结果 132个乳腺结节中，经病理证实恶性60个，良性72个。常规超声通过结节边缘不光整诊断乳腺恶性结节的敏感性86.7%、特异性62.5%、阳性预测值65.8%、阴性预测值84.9%；ABUS通过结节周边“汇聚征”诊断乳腺恶性结节的敏感性60.0%、特异性94.4%、阳性预测值90.0%、阴性预测值73.9%；二者联合诊断乳腺恶性结节的敏感性88.3%、特异性59.7%、阳性预测值65.5%、阴性预测值89.6%，常规超声诊断乳腺恶性结节的敏感性高于ABUS，ABUS诊断乳腺恶性结节的特异性明显高于常规超声和二者联合诊断，差异均有统计学意义（均P＜0.05）。
结论 ABUS较常规超声能提供更加全面的图像信息，对乳腺癌诊断的特异度较高，可作为常规超声的补充。 |

| Abstract: |
| Objective To compare the diagnostic value of automatic breast ultrasound system and conventional ultrasound in the breast cancer.
Methods The preoperative data of conventional ultrasound and ABUS were retrospectively analyzed in 126 patients with 132 breast nodules. The imaging features of conventional ultrasound and ABUS coronal section were analyzed . According to the pathological results as the gold standard, The diagnostic efficacy of ABUS alone and conventional ultrasound and their combination in the diagnosis of breast nodules were calculated and compared.
Results Among the 132 breast nodules that were diagnosed by pathology，60 nodules were malignant and 72 nodules were benign. The sensitivity，specificity，predictive and negative predictive rate of uneven edge detected by US in the diagnosis of breast malignant were 86.7%，62.5%，65.8%，84.9%. The sensitivity，specificity，predictive and negative predictive rate of convergent sign detected by ABUS in the diagnosis of breast malignant were 60.0%，94.4%，90.0%，73.9%. The sensitivity，specificity，predictive and negative predictive rate of combination of the two examination were88.3%，59.7%，65.5%，89.6%. The result indicate that the sensitivity of conventional US was higher than ABUS in the diagnosis of malignant breast nodules，the specificity of ABUS was higher than conventional US and the combination of two examination，the difference was statistically significant（P＜0.05）.
Conclusion ABUS could provide more comprehensive image information than conventional US， and has high specificity for breast cancer diagnosis，it could be used as a supplement to conventional US in the diagnosis of the breast cancer. |
