The traditions in Norway in following trends in the use of radiology and exploring the national differences in examination frequencies and patient doses is reviewed. Norway has had a public founded healthcare system and early access to digital technology included MDCT. The first may explain a moderate examination frequency on the national level, and the second the relatively high collective effective dose (SE) compared to other western countries (1.1 mSv/per inhabitant; 59% from CT). There is substantial variation in examination frequency and doses between counties, radiology institutions and X-ray rooms. This may be explained by several factors: Accessibility and referral strategy (justification), focus on quality, skills and multidisciplinary approaches (optimization), together with equipment related factors. The implementation of diagnostic reference levels are presumed to be a useful tool for optimization locally, and also a source for updated national dose figures in the future. European guidelines on estimating population doses are recently provided [8], a new national survey will be performed accordingly this year. © 2009 Springer-Verlag.
