Observations of significant variability in radiologists' classification of breast density signals the need for objective classification methods. In this study, we develop a model for a radiologist's BI-RADS classification based on the volumetric glandularity image measured by spectral mammography and a reader study where ten MQSA certified radiologists assigned BI-RADS scores to 300 screening cases. Several combinations of features such as area glandularity based on a certain volumetric glandularity threshold, breast thickness and the spread of glandular tissue were tested as linear classifier parameters. Logistic regression was used to optimize the parameters and cross-validation to assess the agreement with the radiologists' majority vote, regarded as truth. We show a clear indication that the automatic classification algorithm performs on par with or better than the average individual radiologist. © 2014 Springer International Publishing.
