Objective
This project is directed towards the following research task as defined in Area D.3.4 of the Nuclear Fission Safety Work Programme: "Development of dose reduction strategies adapted from adult to paediatric palients by deriving a specific technical-clinical basis for the quality criteria concepts; e.g. in CT and image intensifier fluoroscopy." There are existing Working Documents prepared by CEC Study Groups for both adult and paediatric radiology which provide quality criteria for common radiographic images based on "clinical" and "technical" concepts. The clinical criteria are expressed in terms of the degree of visibility of specified anatomical features, thus allowing the subjective assessment of the diagnostic quality of images by radiologists without the need for special equipment. The corresponding technical criteria are ir; the forrn of reference doses for standard-sized adult patients but only for one or two sizes of paediatric patients. Also values for radiographic technique and equipment parameters are recommended which should allow the above image quality and patient dose criteria to be met for a sample of common radiographs. These are based primarily on the judgement and experience of the expert radiologists who drafted the quality criteria documents. To improve the link between the clinical and technical concepts and to provide more quantitative scientific backup to the technical recommendations, this project will involve physical measurements of unage quality and their relation to radiologists' subjective impressions and to patient dose. Special contrast-detail test phantoms and techniques for measuring signal-to-noise ratios will be developed and used to provide more quantitative measures of image quality in radiography, fluoroscopy and CT.
Methods for expressing and measuring reference doses will also be developed for each of these imaging modalities on children and further dose and technique surveys will be conducted in a number of European countries, to extend the currently very limited set of reference doses to other examinations and to a wider range of patient ages/sizes. The usefulness of the reference doses will be extended by providing data for converting them to estimates of radiation detriment for children using computational methods of organ dose calculation in special paediatric phantoms and the latest epidemiological data and risk models.
The CEC Paediatric Quality Criteria Documents will thus be extended to include important high dose examinations involving fluoroscopy, digital radiology and CT. The clinical and technical criteria will be improved in the light of results from the above studies. Finally, the practical impact of implementing the quality criteria at a sample of hospitals will be assessed. The project involves the active collaboration of expert medical physicists from four European countries and a network of dedicated radiologists drawn from the European Society of Paediatric Radiologists.
