目的探讨全自动乳腺容积扫描(ABVS)鉴别诊断乳腺肿块的价值.方法回顾性分析148例乳腺肿块患者共174个病灶的术前ABVS和传统手持探头超声(HHUS)图像特征,将肿块分为良性、可能良性、不能确定、可能恶性和恶性5级,以组织病理学结果为标准,应用受试者工作特性(ROC)曲线评价二者的诊断效果,并对乳腺肿块ABVS冠状面“汇聚征”和“高回声边界”诊断乳腺肿块良恶性的准确性进行评价.结果 ABVS分级诊断乳腺肿块良恶性的ROC曲线下面积(0.927)大于HHUS(0.903)(Z=2.256,P =0.024).ABVS冠状面“汇聚征”诊断乳腺肿块恶性的特异性和阳性预测值均达100％,阴性预测值为0；“高回声边界”诊断乳腺肿块良性的特异性和阴性预测值分别为88.89％和94.51％.结论 ABVS具有较高的临床应用价值,其冠状面乳腺肿块“汇聚征”和“高回声边界”对乳腺肿块良恶性的鉴别诊断具有较高的特异性.

Objective To assess the values of automated breast volume scanner (ABVS) for differentiating of benign and malignant breast masses.Methods A total 174 breast masses in 148 patients were subjected both to conventional handheld B-mode ultrasound (HHUS) and ABVS examinations.The masses were defined as five categories of benign,probably benign,equivocal,probably malignant,and malignant with each method.The results of ABVS and HHUS were compared with pathology.By using the definitive diagnosis and the five levels of suspicion categories,receiver operating characteristic (ROC) curves were drawn to evaluate their diagnostic results.In addition,the diagnostic accuracy for breast masses of futures including retraction phenomenon and hyperechoic rim in coronal plane of ABVS was evaluated.Results The area under the ROC curve of ABVS (0.927) was larger than that of HHUS (0.903) (Z =2.256,P =0.024).The specificity and the positive predictive values both reached to 100％ and false positive rate was 0 with retraction phenomenon,and the specificity and the negative predictive value were 88.89％ and 94.51％ respectively with hyperechoic rim in coronal plane of ABVS.Conclusions ABVS plays an important role in the clinical practice.The retraction phenomenon and hyperechoic rim of breast masses in coronal plane of this new modality have high specialty for differentiating malignant from benign breast masses.
