Study population: Women aged 18 years and above presenting for a diagnostic ultrasound secondary to a palpable mass, abnormal mammogram, follow-up ultrasound abnormality, or discharge were asked to participate in the study.

Brief summary: Women age \>18 scheduled for a diagnostic ultrasound examination had both a hand held ultrasound and an automated breast volume scan. Exams were performed by different technologists. Images were blinded and blinded read for diagnostic accuracy of the two examinations

Detailed description: Women aged 18 years and above presenting for a diagnostic ultrasound secondary to a palpable mass, abnormal mammogram, follow-up ultrasound abnormality, or discharge were asked to participate in the study. If the patient had both a palpable mass and a mammogram that had an abnormality the indication was listed as a palpable abnormality. Exclusion criteria included inability to give informed consent and abnormality of the breast that is larger than one quadrant. No patients were excluded from the study.

All patients received both a Hand Held (HH) and Automated Breast Volume Scanner (ABVS) ultrasound. Patients were initially randomized to have either a HH or an ABVS. The HH ultrasound was performed by one of 4 sonographers that had a minimum of 10 years experience in breast ultrasound. A different sonographer than the one performing the HH or mammography technician performed ABVS. All technologists performing ABVS participated in a training course on ABVS and performed at least 10 patients satisfactorily before beginning the study. The choice of a mammography technician or sonography to perform the ABVS was randomized. Both the sonographer performing the HH and the sonographer or mammography technologist performing the ABVS were provided the patient's history and results of the mammogram if performed for placement of the ABVS and region of interest for the HH. However the results of the HH or ABVS were not available to the person performing the second examination.

Final diagnosis was performed either by a 12 gauge core biopsy (Celero, Hologic, Marlborough, MA ) or confirmation of a benign lesion by no significant change over 2 years.
