In the NHS breast screening programme does radiographer-reported clinical history add value to mammography?

Abstract

Methods Following local research ethics approval, all women attending the assessment clinic for evaluation of a mammographic abnormality found on routine screening (film-screen) were invited to take part in the study subject to informed consent. Participants underwent bilateral two-view two-dimensional (2D) digital mammography and bilateral twoview DBT. Mammography scores using the RCR Breast Group classification were sequentially obtained for the screening mammogram, 2D digital and DBT, and these were each compared with the final assessment outcome. Results Ninety-one percent of eligible women participated. Results from the first 300 participants are presented in Table Kappa coefficients for agreement of each imaging method with final assessment outcome were calculated. Screening mammograms had the lowest agreement with the final outcome (Kappa = 0.02; P = 0.22), 2D digital mammography was better (Kappa = 0.26; P = 0.0000) and DBT had the highest score (Kappa = 0.37; P = 0.0000).
