XXXX initially detected by hand-held ultrasound: detection performance of radiologists using automated breast ultrasound data.

@entity1 @entity5 @entity0
BACKGROUND: Ultrasonography (US) has been used as an important adjunct to mammography (MG), and automated breast US (ABUS) scanners were originally designed to effectively examine the breast in its entirety. PURPOSE: To retrospectively assess the performance of radiologists in the detection of @entity0 , initially detected by hand-held ultrasound (HHUS), using 3D breast volume data obtained from a commercial ABUS system. MATERIAL AND METHODS: Bilateral whole breast US was performed using ABUS in 61 consecutive @entity1 who were scheduled to undergo US-guided needle biopsy due to suspicious breast masses detected during screening HHUS. Fourteen @entity5 in 13 @entity1 and 48 normal breasts of 48 @entity1 with benign disease in the contralateral breast were selected. Three radiologists who had not performed the HHUS examinations independently reviewed the 3D ABUS data for any lesions that required recall for further evaluation. Sensitivities and false-positive rates were calculated. RESULTS: The sensitivities of the three readers for @entity5 detection were 78.6% (11/14), 78.6%, and 57.1% (8/14), respectively, with false-positive rates of 20.8% (10/48), 12.5% (6/48) and 8.3% (4/48). Seven @entity5 were detected by all three readers, four @entity5 by two readers, and one @entity5 by one reader. Two invasive @entity5 were not detected by any reader. CONCLUSION: Of HHUS-detected @entity5 , only 57.1-78.6% were identified with ABUS. A substantial level of experience and training is necessary to improve @entity5 detection by ABUS.
