[Is telemammography an option for screening programs?--A phantom study].

Purpose: To show that it is possible to proceed a 20-fold JPEG 2000 wavelet compression of radiographs of a CDMAM phantom without data loss and the usefulness of this technique in telemammography for screening.
Material and Methods: After digitizing and a 20-fold data compression, four radiographs of a CDMAM phantom were transferred via ISDN to a PACS archive. Using a soft copy work station, the contrast detail detectability of these data sets was compared to the contrast detail detectability of the original radiographs.
Results: The contrast detail detectability showed no difference for the original radiographs and the data sets.
Conclusion: It is possible to digitize radiographs of a contrast detail mammography phantom, to compress the data sets, to transfer them to a soft copy station and to decompress them without negative influence on the contrast detail detectability.
