To prospectively evaluate the detectability and performance of automated breast US scanner and compare it with hand held breast US in suspicious calcifications on mammography.

Forty-two patients with 43 breast lesions, scheduled for US guided or stereotactic biopsy for suspicious calcifications on mammography, underwent automated breast US and hand-held US examination. Two radiologists reviewed the automated breast US data in consensus. A radiologist who had not performed the hand-held US examination reviewed hand-held US data. Detectability and diagnostic performance of automated breast US and hand-held US were calculated.

Among 43 lesions, 25 (58.1%) were malignant and 18 (41.9%) were benign. Detection on ABVS was more frequent for lesions; malignant vs. benign (96.0% [24/25] vs. 44.4% [8/18], p=0.002), of maximal extent more than 10mm (86.7% [26/30] vs. 46.2% [6/13], p=0.009), or lesions with fine pleomorphic or fine linear shape vs. round or amorphous or coarse heterogeneous shape (94.7% [18/19] vs. 58.3% [14/24], p=0.021) at mammography.No significant difference was found in AUC between automated breast US (0.758, 0.603-0.875) and hand-held US (0.786, 0.634-0.896) (p=0.571).

Automated breast US detected 96.0% (24/25) of malignant calcifications on mammography. Detection was found to be related to the pathology, to calcification extent, and shape at mammography.

This study is the first study to compare the detectability and diagnostic performance for suspicious microcalcifications between ABVS and HHUS. ABVS showed similar diagnostic performance to HHUS.
