Accuracy of determining preoperative XXXX extent measured by automated breast ultrasonography.

PURPOSE: The aim of this study was to determine the accuracy of measuring preoperative @entity5 extent using automated breast ultrasonography (US). MATERIALS AND METHODS: This retrospective study consisted of 40 @entity1 with histopathologically confirmed @entity0 . All of the @entity1 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 @entity5 size included not only the invasive foci but also any in situ component and was used as the gold standard. The discrepancy of the @entity5 extent between automated breast US and the histological examination was calculated. RESULTS: Automated breast US enabled visualization of the @entity0 in all @entity1 . The mean size of the lesions on US was 12 mm (range 4-62 mm). The histopathological diagnosis was @entity513 in situ (DCIS) in seven @entity1 and @entity513 in 33 @entity1 (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 @entity5 extent with a deviation in length of <2 cm was 98% (39/40). CONCLUSION: Automated breast US is thought to be useful for evaluating @entity5 extent preoperatively.
