INVITED Evolution of Quality Assurance in Paediatric Radiology [Elektronische Daten] [K. Schneider (INVITED)] Quality assurance in diagnostic radiology has become increasingly important over the last 10 years. It is vital, especially in paediatric radiology, to make the right selection of radiographic examinations and their proper sequence and, furthermore, to adapt the radiographic technique to the special requirements of paediatric patients. As part of a quality control programme, several field study surveys were conducted and the X ray equipment was evaluated in a total of 180 clinics and doctors' offices in Germany in the period between 1988 and 1992. For this purpose, measurements of the entrance surface dose (ESD) using a patient equivalent Teflon phantom were taken for seven frequent X ray examinations in infancy. The dose values varied extensively in all examinations. Similar variations were found for general radiologists and other physicians who X ray children, but the mean doses were three times higher than the mean doses found for paediatric radiologists. An initiative of the Commission of the European Communities (CEC) led to the definition of image quality criteria and parameters for good radiographic technique for frequent X rays as part of the development of Quality Criteria in Paediatrics (Working Document of the CEC). This allowed a direct evaluation of the relation between the measured ESD and image quality. The analysis from two European Community-wide surveys in about 90 childrens' clinics showed similarly wide dose variations as in the above mentioned national surveys. The Commission of the European Community now has the responsibility to make use of these results to induce effective quality assurance programmes in its member states.
