Digital mammography versus digital breast tomosynthesis for detection of XXXX in the intraoperative specimen during breast-conserving surgery.

@entity433 @entity1 @entity3821 @entity0
PURPOSE: To compare the diagnostic ability of specimen radiography using @entity433 ( @entity433 ) and digital breast tomosynthesis (DBT) for detecting @entity0 and evaluating its extension in the intraoperative specimen. METHODS: Sixty-five specimens from 65 @entity1 (median 62  years; range 34-86) obtained during breast-conserving surgery were prospectively investigated. Specimens underwent @entity433 (25-40 kVp, 12-322 mA  s) and DBT (25-34 kVp, 13-137  mA) in two orthogonal planes, anteroposterior (AP) and latero-lateral (LL). Images were interpreted by a radiologist to detect invasive lesions and their extensive @entity3821 in situ ( @entity3821 ); afterwards, they were compared with histopathological findings. RESULTS: In AP views, 96  % of the invasive lesions were detected by both the methods. Of the EICs, 55 and 65  % were detected by @entity433 and DBT, respectively (P  =  0.61). Of the DICSs, 31 and 38  % were detected by @entity433 and DBT, respectively (P  >  0.99). In LL views, 71 and 13  % of the invasive lesions were detected by DBT and @entity433 , respectively (P  <  0.0001). Of the EICs, 42 and 10  % were detected by DBT and @entity433 , respectively (P  =  0.0078). Of the 13 DCISs, 42 and 8  % were detected by DBT and @entity433 , respectively (P  =  0.32). The whole lesion and contour could be delineated in 45  % by DBT and in 6.2  % by @entity433 (P  <  0.0001). CONCLUSIONS: DBT could detect @entity0 more accurately than @entity433 in LL views, indicating its potential to more precisely diagnose vertical invasion.
