An IRSN team (PRP-HOM/UEM) working with physicists from several medical centers  won the jury's "special mention" for its electronic poster presented during the Journées Francophones de la Radiologie (JFR) in Paris in October 2016. Among the 700 posters on display during the event, it was one of the most viewed by participants.
The poster, "Breast Digital Tomosynthesis: Dose and Internal Quality Control", highlighted the findings of a study aiming to assess various 3D mammography systems in terms of dose and image quality, as well as to evaluate several phantoms that could be recommended for quality control. Many centers in France already offer Breast Digital Tomosynthesis (DBT), and the introduction of this technique within the French breast cancer screening program is being considered by the authorities in the coming years. Quality control protocols must therefore be developed for this technology.
The study has shown that the diversity in design of DBT systems leads to variability in terms of image quality and dose depending on breast thickness. Therefore it seems necessary to monitor DBT systems on a regular basis. Moreover, two phantoms exhibit interesting features for internal quality control.
Organized by the Société Française de la Radiologie (SFR), which promotes scientific advances in radiology, the yearly JFR event is a major event for French and French-speaking radiology specialists.

 Breast Digital Tomosynthesis is a new breast imaging technology that some clinical studies say offers more sensitive and specific cancer detection because the superimposition of tissue is reduced compared to 2D mammography.
