6 th <strong>International</strong> <strong>Workshop</strong> on Breast Densitometry and Breast Cancer Risk Assessment heterogeneously dense and dense breast tissue, and to formulate recommendations when no science was available to guide policy. Materials and Methods: The CBDIG task was to review existing scientific literature to provide evidence-based recommendations for guiding health care providers and women regarding supplemental screening after notification, and to formulate recommendations when no science was available to guide policy. Each facility then developed their own policy to respond to SB 1538, which was implemented in California on April 1, 2013. Results: After breast density notification, Figure 2: NCCN, ACS and ACR Guidelines CBDIG recommended women and health care for Breast Cancer Screening after Normal providers to consider supplemental breast Screening Mammography cancer screening based on breast cancer risk assessment (6) using family history models (7,8) based on recommendations from nationally High risk (> 20% lifetime) – MRI* Intermediate risk (15-20% lifetime ) – possible MRI** recognized guidelines (7,8,9) (Figure 2).

P26 6 th <strong>International</strong> <strong>Workshop</strong> on Breast Densitometry and Breast Cancer Risk Assessment CHALLENGES IN DE-IDENTIFYING FILM-SCREEN MAMMOGRAMS PRIOR TO BREAST DENSITY ASSESSMENT FOR THE NOVICE PRACTITIONER J Jobling, C D’Este, JF Forbes School of Medicine and Public Health, University of Newcastle, NSW Australia Introduction: Measurement of breast density on mammograms presents many challenges. Film-screen mammograms require conversion to digital format prior to assessment with computer software, but contain burned-in areas of identifying information that should be removed to protect participant privacy. We are undertaking a retrospective linkage study in at least 4,000 women between the lower Hunter New England (NSW Australia) BreastScreen and the NSW 45 and Up Study to examine longitudinal changes in breast density and breast cancer risk. The BIRADS density categories are not routinely employed in Australia hence density will be assessed via the Cumulus software and/or visual methods. A simple, efficient and inexpensive method to de-identify thousands of film-screen mammograms is needed. Coverage of identifying areas on film with standard sticky labels during digitisation on an Array 2905HD laser scanner is not effective due to the strength of the laser. Our aim was to evaluate a range of software programs available for this purpose. ABSTRACTS Methods: Software capable of quickly and easily batch de-identifying digital images in DICOM format was sought via general internet searches using the terms ‘DICOM anonymizer burned in’; searches in PubMed using similar terms were also undertaken. Software was evaluated by: 1) its capacity to easily batch de-identify DICOM images with burned-in identifying areas (i.e. digitised film-screen mammograms), 2) the ability to easily remove DICOM header information from digital mammograms, and 3) retention of detail and compatibility with the Cumulus software post-processing. Results: More than 60 free DICOM viewers and 20 de-identifiers/anonymisers were identified (dclunie.com). Searches in PubMed found two useful, recent (
