[Consensus Meeting of Course Directors in Breast Imaging, 9 May 2009, in Frankfurt am Main - Topic: Masses].

Fourteen directors of breast imaging courses met on behalf of the German Society of Radiology to discuss the actual standards of the diagnosis of masses. Open questions on the fields of mammography, breast ultrasound and breast MRI were elucidated by a presentation of one of the 14 panel members, followed by an electronic anonymous voting. Beside of the panel members, more than 300 participants of the consensus meeting contributed their opinions by electronic voting. Answers with definite majorities (> 75 %), answers with narrow majorities and those with missing majorities were discriminated from each other. The opinions of the plenum were compared to the majorities of the podium and showed only a few critical differences. Due to unequivocal majorities seven answers to important questions concerning the diagnosis of masses can lead to a further standardization of breast cancer diagnosis.
