Mammography Positioning: The CC and MLO

The American College of Radiology (ACR) instituted a volunteer accreditation process for mammography facilities which began in 1987. The college paved the way for MQSA regulations, which all facilities in the United States are now regulated by. There are many criteria required for a mammography facility to be accredited. Clinical image review is one of those criteria. Although mammography patient positioning is the one element that is practiced most frequently, it is the one criteria that is shown to be most deficient. A thorough review of proper positioning of the craniocaudal and mediolateral oblique views for the screening mammography patient will be discussed in detail.
