The aim of this study was to investigate the extraclinical value of automated breast volume scanning (ABVS) in the diagnosis of breast tumor compare to hand-handle ultrasound (HHUS).

One hundred twenty-four patients with breast tumor were performed HHUS and ABVS before operation. The research focused on whether there were newly found tumors or new findings on the coronal planes by using ABVS compared with HHUS. Then, the classification adjustments of breast imaging reporting and data system (BI-RADS) were made according to new findings on the coronal planes by using ABVS.

There are totally 166 breast tumors found in 124 patients by HHUS, while 8 more were observed by ABVS, 4 of which were malignant and the rest were benign. The sensitivity and specificity of ABVS coronal plane findings were 37.0% and 92.5%, respectively. The area under receiver operating characteristic curve was 0.89 before the corrected classification versus 0.93 after the corrected classification, there were no significant differences (P > .05).

There was no significant extraclinical value in differentiating diagnosis of malignant tumors and benign breast tumors by ABVS comparing to HHUS. However, those minimal lesions missed diagnosis could be found by ABVS with continuously automatic scanning.
