Our aim was to investigate the diagnostic potential of automated breast volume scanning (ABVS) and compare it with manual ultrasound (US) and mammography.
One hundred and fifty-five patients with a total of 165 breast lesions had mammograms, manual US and an ABVS. Multiplanar reconstructions in coronal, transverse and sagittal views were reconstructed from the automated data set. After biopsy or surgery, all lesions were confirmed histologically. Data were evaluated according to the Breast Imaging Reporting and Data System (BI-RADS) classification. Detection rate, diagnostic accuracy, sensitivity, specificity and positive (PPV) and negative (NPV) predictive value of each method were analysed.
Detection rate, diagnostic accuracy and mammography sensitivity were significantly lower than those of each US method (p<0.05). There were no significant differences between manual US and ABVS. When combining ABVS, US and mammography, diagnostic accuracy, sensitivity and specificity reached 96.4%, 97.1% and 95.2%, respectively. A spiculated and stellate margin in the coronal plane has a high specificity in diagnosing malignant lesions.
ABVS can provide additional information in the differential diagnosis of a lesion. It has significantly higher sensitivity than mammography, but it is similar to manual US and cannot be preferred to a manual US examination.
本研究旨在探讨自动乳腺容积扫描（ABVS）的诊断潜力，并将其与手动超声（US）和乳腺 X 线摄影进行比较。
155 例共 165 个乳腺病变患者均接受了乳腺 X 线摄影、手动 US 和 ABVS 检查。从自动数据集重建冠状、横断和矢状多平面重建。活检或手术后，所有病变均经组织学证实。根据乳腺影像报告和数据系统（BI-RADS）分类评估数据。分析每种方法的检出率、诊断准确性、敏感性、特异性以及阳性（PPV）和阴性（NPV）预测值。
检出率、诊断准确性和乳腺 X 线摄影敏感性均显著低于每种 US 方法（p<0.05）。手动 US 和 ABVS 之间无显著差异。当联合 ABVS、US 和乳腺 X 线摄影时，诊断准确性、敏感性和特异性分别达到 96.4%、97.1%和 95.2%。冠状面呈棘状和星状边缘的病变具有高度的恶性病变特异性。
ABVS 可为病变的鉴别诊断提供额外信息。其敏感性显著高于乳腺 X 线摄影，但与手动 US 相似，不能优先于手动 US 检查。
