Diagnostic radiology in Sweden is changing rapidly to digital (filmless) technique. The advantages are more rapid delivery of radiologic service, better working conditions and less negative effects on the environment. Teleradiology is also facilitated. The Swedish Board of Health and Welfare has investigated the speed with which this change is taking place. In 1998, 26 of the 118 departments of diagnostic radiology had already turned digital; it is estimated that in the near future at least five departments will become fully digital each year. For planning purposes, less emphasis should be put on the supply of radiographic film, and more on telecommunications, computer hardware and digital storage.
