Breast Cancer
Conditions
Brief summary
The purpose of this image acquisition study is to compare, in a Reader Study, the RI8 system used in conjunction with a conventional mammography to mammography alone, and to determine whether the addition of supplementary RI8 result will improve ROC area under the curve. The study is prospective, multi-center, sequential, control trial with the woman serving as her own control. Women determined to have heterogeneously or extremely dense breast based on her previous mammogram and are undergoing routine screening mammography at one of the clinical sites assigned for this study will be eligible to join the study.

Inclusion criteria
A. Subjects whose most recent (within 18 months) prior mammogram interpreted as heterogeneously dense (ACR BI-RADS Breast Density C) or extremely dense (ACR BI-RADS Breast Density D) breast tissue. AND B. Subjects who are asymptomatic and scheduled to undergo routine screening mammography. OR C. Subjects scheduled for image-guided needle biopsy as a result of findings obtained during standard of care imaging modalities (mammography, ultrasound and/or MRI) performed at the clinical site that participates in the study.

Subjects who participated in the Validation Phase will not be able to participate in the Testing Phase
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Difference in the area under the ROC curve when comparing mammography plus RI8 result to mammography alone. | 18 months |
| All adverse events and serious adverse events caused by the imaging session as judged by the physician. | 18 months |
Secondary
| Measure | Time frame |
|---|---|
| Sensitivity and specificity will be computed based on the forced BI-RADS assessment of each mammography case alone and mammography plus RI8. | 18 months |
Other
| Measure | Time frame |
|---|---|
| Sensitivity and specificity of the device will be determined from all enrolled cases. Upper and lower estimates will be determined based on missing data. | 18 months |
