Abstract
Quality management systems in the 21st century should not be unwieldy and over-documented tomes, but should be used to reflect the organisation's policy, objectives and commitment to quality. Quality management systems should be used as the basis for continually improving business performance with a more flexible 'process based' management approach rather than the earlier, somewhat regimented, 'system based' style. Our aim, through the use of illustration, is to provide an informative view of the requirements of the 21st century quality management system [1] and the role and responsibilities of the quality manager.

Histological analysis of core biopsy of breast lesions takes a minimum of 24 h, but imprint cytology of a core biopsy can be reported within an hour
A total of 450,425 women were screened by BreastScreen Western Australia (BSWA) from January 1990 to December 2000. 2,314 cancers were detected with a total cancer detection rate of 5.1 cancers per 1,000 women screened. 4,916 women of ATSI origin were screened during this interval. 31 breast cancers were diagnosed, with a total cancer detection rate of 6.3 cancers per 1,000 women screened
These lesions may mimic the microcalcifications of ductal carcinoma in situ at screening mammography
Summary
Histological analysis of core biopsy of breast lesions takes a minimum of 24 h, but imprint cytology of a core biopsy can be reported within an hour. This study validates the accuracy of imprint cytology from core biopsy of breast lesions obtained under ultrasound control. Full field digital mammography (FFDM) seems set to replace conventional film-screen technique. Concern has been raised over FFDM diminished spatial resolution (5–6 Ip/mm). If valid, this could compromise detection of calcification and diagnosis of ductal carcinoma in situ (DCIS). In our centre we were not able to perceive any difference between microfocus magnification and on-screen magnification when assessing microcalcification. We subsequently compared these results with average scores for over 90 film-screen mammography systems
