In 1990 the region of Tuscany instituted a quality control program for mammography, in order to check the working conditions of mammography centers in the region, to investigate the feasibility of applying some working standards in line with European recommendations, and to promote the training of personnel. The program involves the following: a test of newly acquired mammographic equipment to establish that it meets the required standards; an annual test of generators, X-ray beams, grid, AEC, screen-film system, film processing, dose and image quality; daily test (phantom radiography and film sensitometry) performed by the personnel of each mammographic Unit; and a sustained advisory service for the technical problems occurring between checks. Thirty-nine of 57 centers participated on a voluntary basis, and 135 checks were performed annually. The results of the program show a performance below the recommended standard in relation to AEC, film sensitometry and the adequacy of lights in dark rooms in 40%, 50% and 63%, respectively, of the centers. Entrance exposure was over 1500 mR, with a maximum value of 3450 mR, in 6 cases in the first round. 5 cases in second, and only 1 case in the third. In general, the results are slightly improving, but mammography optimization is still a long way off. It is necessary to carry out suitable programs for quality control in mammography on a regional basis and to establish precise guidelines for individual mammographic Units to follow in order to meet the European standards.
