The current state of the art for breast imaging is reviewed in comparison w
ith the methods of practice commonly in use 25-35 years ago to demonstrate
the most important advances that have taken place in imaging techniques, op
erational considerations, interpretive approaches, and interventional proce
dures. Since 1965, breast imaging has progressed from the simple assessment
of breast disease in a selected small number of symptomatic women to the c
omprehensive evaluation of both breast health and disease in a substantial
percentage of all women aged 40 years and older. In the process, breast ima
ging has become an established radiologic subspecialty that accounts for at
least 10% of all examinations performed by radiologists. Indeed, mammograp
hy now is the most common imaging examination that directly results in the
reduction of mortality from disease.
