| 目的：探讨自动乳腺全容积超声（ABUS）在乳腺微小结节良恶性诊断中的价值。方法：回顾分析我院2016年8月至2019年11月期间收治的75名乳腺微小结节（结节最大径≤1cm）患者，所有患者均自愿接受二维超声检查及ABUS检查，对照病理检查结果，分析二维超声检查与ABUS在微小结节检出率及良恶性诊断中的差异。结果：75名乳腺微小结节患者，手术证实微小结节共96个，其中最大径0.5cm-1cm结节65个，＜0.5cm结节共31个。二维超声检测共发现89个结节（0.5-1cm 62个，＜0.5cm 27个），ABUS检测发现96个结节，二维超声检出率（92.71%）低于ABUS小结节检出率（100.0%），两种超声检查对小结节良恶性诊断对比病理结果，二维超声检测诊断灵敏度为80.77%（21/26），特异度为95.24%（60/63），诊断符合率为91.01%（81/89），ABUS诊断灵敏度为89.29%（25/28），特异度为98.53%（67/68），诊断符合率为95.83%（92/96），两种检查方法相比差异有统计学意义（P＜0.05）。二维超声在结节直径＜0.5cm以及乳晕区、结节距乳头位置较远时微小结节检出率较ABUS低。结论：自动乳腺全容积超声相较于二维超声能够避免操作者依赖，更准确的诊断微小结节的良恶性，为早期诊断微小乳腺癌提供依据。 |

| Abstract: |
| Objective: To explore the value of automated breast ultrasound system (ABUS) in the diagnosis of breast minimum nodules. Methods: a retrospective analysis of 75 patients with breast minimum nodules admitted to our hospital from August 2016 to November 2019 was carried out. All patients were examined by ABUS and 2D breast ultrasound to detect the location of the lesions, then diagnosis benign and malignant lesions.The results were compared with the postoperative pathological results (the gold standard). Results: There were 75 patients with 96 minimum nodules which were confirmed by surgeries. The maximum diameters of 65 nodules were 0.5-1.0cm, 31 ones were less than 0.5cm. 89 lesions were found by 2D ultrasound, 96 lesions were found by ABUS. The detection rate of 2D ultrasound (92.71%) was lower than ABUS (100%). Compared to pathology results of lesions, sensitivity, specificity and accuracy rate of 2D ultrasound were 80.77% (21/26),95.24%(60/63) and 91.01%(81/89). The sensitivity, specificity and accuracy rates of ABVS were 89.29%(25/28),98.53%(67/68) and 95.83%(92/96). There were significant differences between these two methods(p＜0.05). For localization diagnosis, the missed diagnosis parts of minimum nodules by 2D ultrasound were mammary areola part and 4.5cm far from nipple when compared to ABUS. Conclusion: ABUS can avoid operator dependence, and diagnosis minimum nodules accurately, which can provide the basis for early diagnosis of small breast cancer. |
