Sites available on the Internet are constantly increasing and over 15,000 medical websites covering all medical sub-specialties are now available. Finding relevant information on the web may be time consuming and difficult. We suggest that new users begin by accessing servers where lists of available sites are grouped under headings such as medical sub-specialties. We will list a selection of useful radiological websites providing image databases, case reports, radiological anatomy and continuing medical education. While surfing on the web, an evaluation of the quality of the websites is necessary. We used the quality criteria proposed by Darmoni to rate the quality of ten websites. The overall quality was good, but the lack of help options and external links were the main pitfalls that we noted. All webmasters should pay attention to quality criteria and show the Darmoni criteria on their homepage. In order to evaluate which internet options should be developed, we evaluated our own website and submitted a questionnaire to our users. Clinical cases were the most requested feature, they could be used for continuing medical education.
