A quality assurance program is an integral part of a department of rad
iology, but certain examinations require a more specialized approach t
han others. The need for greater quality control in mammography was re
cognized by the American College of Radiology in 1987. The voluntary p
rogram developed by this organization has greatly improved the overall
quality of mammography in almost three fourths of the facilities in t
his country. The principles of this initiative now have been adopted b
y various state and federal agencies, but a uniform approach has not y
et been finalized. Optimally, the best aspects of all of these program
s will be integrated, resulting in satisfactory image quality, accepta
ble dosimetry, and an appropriate level of interpretive accuracy in al
l mammography installations.
