Pilot Mammography Reader Study to Assess Breast Cancer Detection in FFDM Plus DBT Versus FFDM Alone

This pilot reader study was to determine the following:

the radiologist's performance metrics for the two reading modalities, i.e., "FFDM read on the Aspire Bellus workstation" and "FFDM read in conjunction with DBT read on the Aspire Bellus workstation",;
the magnitude and direction of differences between performance metrics for the two modalities; and
variance components and correlations that would influence samples sizes and case mix for the subsequent pivotal reader study comparing performance metrics between the two modalities.
