National Mammography Database for Breast Screening
Official title: National Mammography Database
Run by American College of Radiology · NCT01900821 · Data updated 2026-11-12
This program collects mammogram data from breast imaging centers to give them semi-annual feedback comparing their cancer detection, recall, and positive predictive values to national benchmarks.

Is this trial a fit for you?
✓Likely a good fit
Ideal participants are breast imaging centers—especially ACR-designated Breast Imaging Centers of Excellence—that routinely perform and can submit screening and diagnostic mammography data.
✕Probably not a fit
Individual patients may not receive direct clinical benefit from participation, particularly if their imaging facility does not contribute data or if data-driven changes are not implemented locally.

What this trial studies
The American College of Radiology's National Mammography Database aggregates data that radiology practices already collect under federal mandates to create national and regional benchmarking reports. Participating centers submit screening and diagnostic mammography metrics and receive semi-annual feedback reports including cancer detection rates, positive predictive value, and recall rates. Participation is free for facilities designated as Breast Imaging Centers of Excellence (BICOE). The project is observational and aims to improve quality of mammography through regular performance comparison rather than changing individual patient care.
Why it matters
Potential benefit: If successful, this program could help imaging centers improve screening accuracy and reduce unnecessary recalls, leading to earlier cancer detection and fewer false positives for patients.
How similar studies have gone: Similar national registries and quality-benchmarking programs, such as the Breast Cancer Surveillance Consortium, have been used to track performance and improve mammography quality, so this approach is established.

How breast density affects mammogram screening and follow-up
This project will test whether women aged 45–75 with dense breasts have more recalls and additional diagnostic tests after routine mammograms than women with less dense breasts.
-
Single radiologist with AI support versus two radiologists for screening mammograms
This trial will see if one radiologist aided by AI can match the performance of the usual two-radiologist reading for screening mammograms in women aged 45–69.
-
Contrast-enhanced mammography versus MRI for breast surveillance in high-risk women
This trial will test whether contrast-enhanced mammography can replace MRI plus digital mammography for annual breast screening in women aged 35–60 with a five-year breast cancer risk of ≥5%.
How to take part
- Review the eligibility criteria above with your treating physician.
- Check the official listing on ClinicalTrials.gov for the latest contact details and recruitment status.
- Contact the study coordinator or principal investigator to ask for pre-screening. Pre-screening is free and never obligates you to enroll.
