Data obtained from a survey involving 6 organizations enabled determination of the number of french radiologists in practice at the present time, and the establishment of regional lists of their office premises. The latter varied according to availability of personnel, the climate, the population density and the available radiology schools. Pyramid graphs provided data on age and sex of radiologists and were used to determine the incidence of turn-over for the specialty. National and departmental density of radiologists was also calculated. Total quantitative data obtained will be used as a base for all future projections able to define a true radiologic policy in France.
