About this study
Official title: A Multi-Reader Multi-Case Controlled Clinical Trial to Evaluate the Comparative Accuracy of the Fujifilm Full Field Digital Mammography (FFDM) Plus Digital Breast Tomosynthesis (DBT) Versus FFDM Alone in the Detection of Breast Cancer
The purpose of this pilot is to provide credible performance estimate information in order to conduct subsequent reader studies.
Read the detailed description
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.
- Conditions
- Breast Cancer
- Being tested
- FFDM Plus DBT, FFDM

What is being measured
The primary outcome is the main question the study is designed to answer.
Compare Per Subject Area Under Curve (AUC): FFDM Only vs DBT Plus FFDM
Breast AUC performance metrics to determine if FFDM plus DBT improved cancer detection rate, requiring correct lesion localization. Statistician to estimate AUCs for each reader in each review condition (FFDM read in conjunction with FFDM plus DBT read) based on their Probability of Malignancy (POM) scores. POM scores will require correct lesion localization, such that in a case with cancer if the reader recorded one or more findings in the case but none of them are determined by the truther to match the location(s) of any proven malignancies, a POM score of 0 will be assigned to the case. Statistician to provide graphical representations of each reader's ROC curve for each review condition. For each reader the difference between the AUC for the FFDM read in conjunction with the FFDM plus DBT will be presented. Statistician to perform MRMC comparison of AUC's between FFDM read in conjunction with FFDM plus DBT using the MRMC method of Dorfman, Berbaum \& Metz (1992).
