Abstract

This retrospective study consisted of 40 patients with histopathologically confirmed breast cancer All of the patients underwent automated breast US ABVS Siemens Medical Solutions Mountain View CA USA on the day before the surgery The sizes of the lesions on US were measured on coronal multiplanar reconstruction images using the ABVS workstation Histopathological measurement of tumor size included not only the invasive foci but also any in situ component and was used as the gold standard The discrepancy of the tumor extent between automated breast US and the histological examination was calculatedAutomated breast US enabled visualization of the breast carcinomas in all patients The mean size of the lesions on US was 12 mm range 4–62 mm The histopathological diagnosis was ductal carcinoma in situ DCIS in seven patients and invasive ductal carcinoma in 33 patients 18 without an intraductal component 15 with an intraductal component Lesions ranged in diameter from 4 to 65 mm mean 16 mm The accuracy of determination of the tumor extent with a deviation in length of 2 cm was 98 39/40
