Abstract
The digital archiving has great advantages compared to the standard 35-mm X-ray cinefilm documentation. The data are immediately available and quantitative coronary angiography possible. In addition the technical progress is enhancing the availability of data. The loss of films is nearly eliminated, as only copies of the digital archive data are delivered. In addition a big advantage concerning pollution is present, when CD Rs are used. We report about the damage of CD Rs after 89, 162, 181 and 252 days when they were stored in polypropylene material containing envelopes. The damaged CD Rs all belonged to the provider Verbatim, whereas CD Rs of the provider Rank Xerox or Kodak were never damaged. In contrary to the Verbatim company, Rank Xerox gave written confirmation for 10-year storage and a written confirmation, that the storage in the polypropylene envelopes is possible. Mechanical, thermal damage and damage by humidity have to be discussed as well as chemical interactions of the CD Rs surface with the polypropylene material. As the digital storage for X-ray images has to be provided for 10 years in Germany, it is concluded, that the storage in polypropylene envelopes has to be avoided, when a written confirmation by the company is not given. These observations should stimulate to better control and analyze the real storage availabilities of digital data and provide in the future other media than CD R for long-term archiving.
