THE ROLE OF IMAGING IN SCREENING SPECIAL FEATURE: FULL PAPER Breast compression across consecutive examinations among females participating in BreastScreen Norway

摘要

t Objective: Breast compression is used in mammography to improve image quality and reduce radiation dose. However, optimal values for compression force are not known, and studies have found large variation in use of compression forces between breast centres and radiographers. We investigated breast compression parameters, including compression force, compression pressure and compressed breast thickness across four consecutive full field digital mammography screening examinations for 25,143 subsequently screened females aged 50-69 years.
