摘要：Aims: Magnetic resonance imaging (MRI) is one of the non-ionising radiation techniques whose use is recommended by the European Directive 97/43/Euratom instead of ionising radiation techniques. In 2005, specialist research institutes published a Good Use Guide for Imaging Examinations in this regard. Our objective was to draw up an inventory of all MRI activities and to analyse the indications of examinations.Methods: This was a cross-disciplinary study based on the activity registers of ten MRI devices in the Champagne-Ardenne region, from January to September 2006. Using a stratified random sample, we compared the reasons given for the examination in the report withthe recommendations.Results: We listed 41,181 MRI examinations. The average number of daily examinations was 151 (median: 198, maximum: 243). Emergency examinations were rare. Neurological disorders accounted for 25.7% of examinations [confidence interval at 95% (CI95): 22.5%; 28.9%], osteoarticular problems 24.7% [CI95: 21.5%; 27.9%] and cancers 7.5% [CI95: 5.0%; 9.5%]. Clinical situations justifying the examination were provided for in the Good Use Guide in 72.3% of cases [CI95: 69.0%; 75.6%].Conclusion: The annual number of MRI examinations per 1,000 inhabitants was less than in the US, but more than in Canada and Great Britain. Although the availability of MRI devices seems adequate for the diagnosis of strokes, prostate cancers and child epilepsy, it is inadequate for other cancers, cardiovascular problemsand emergencies. This calls for the installation of new MRI devices.Prat Organ Soins 2008;39(4):311-321
