Purpose: To evaluate a fully integrated digital screening mammography program (image acquisition, transfer and over-read).
Materials and methods: between april 2005 and December 2007, two imaging sites were authorized by the Department of Health to use digital mammography units (Senographe 2000D and 2000DS, GEMS) for screening mammography. the initial interpretation was made on a workstation with accompanying digital films. The images were also transmitted via the internet on the same day for over-read on a workstation. In addition, a <<classical>> over-read was also performed from printed mammographic images using a viewbox. Differences in interpretation and BIRADS classification as well as economical considerations were analyzed between the types of interpretation setups.
Results: A total of 7008 screening mammograms were included. No significant problem was reported with regards to internet image transfers. No significant interpretation difference was noted related to the fully integrated digital imaging process. This technology could generate cost savings estimated in 2007 at 3.793/year (mailing fee).
Conclusion: A fully integrated digital screening mammography program results in improved organisational processes and significant cost reductions without reduced diagnostic accuracy.
