[Methodology in gastrointestinal radiology. Suggestion for standards and preliminary results]

The Marche SIRMN group tried to set up standard of some common radiological examinations (cholecystography, single and double contrast examination of the upper gastro-intestinal tract, and single and double contrast enema). Scientific and professional reasons led to this work. Twenty-five radiologists from thirteen centers in the Marche region cooperated on it. Some differences between the plan and the real performance of the standard radiological examinations as well as between technical and methodological performance came out. Eventually preliminary and partial data about the cost of the procedures and the final diagnostic result were obtained.
