Use of Tomosynthesis in Intraoperative Digital Specimen Radiography - Is a Reduction of Breast Re-excision Rates Possible?

ABSTRACT: Aim: A prospective clinical study was done to see whether it is possible to reduce the rate of re-excisions using digital breast tomosynthesis (DBT) compared commercial FFDM. Material and Method: Between 1/2011 and 5/2011 we diagnosed an invasive breast cancer (BI-RADS 5) in 100 patients. After histological verification we performed breast-conserving therapy with intraoperative imaging using one of 2 different systems: 1. Tomosynthesis (Siemens, Erlangen, Germany), amorphous selenium, Tungsten source, focus 0.1 mm, resolution 85 µm, pixel pitch, 8 l/mm, range: 50°, 25 projections, time for scanning > 20 s, geometry: same scanning scope, reconstruction: filtered back projection; or 2. Inspiration™ (Siemens, Erlangen, Germany), amorphous selenium, tungsten source, focus 0.1 mm,
