NRDR Portal Offline

The NRDR portal will be down for maintenance starting April 5th, 2025 at 8am ET and ending April 7th, 2025. All functions of NRDR will be unavailable, to include NRDR Uploader, DIR Link, Assess-AI, DIR Exam Name Mapping, and the MIPS portal. Data submitted to DIR Link will be automatically resubmitted once maintenance has been completed.  Data submitted to Assess-AI will have to be resubmitted by the facility.  

If you experience any issues with the NRDR portal after maintenance is complete, please request support at nrdrsupport.acr.org. For issues submitting data to Assess-AI, please contact David Markovich at dmarkovich@acr.org.

The National Mammography Database (NMD) leverages data that radiology practices are already collecting under federal mandate to provide them with comparative information for national and regional benchmarking. Participants access feedback reports that include valuable benchmarking data such as true positive rates, positive predictive value rates and recall rates.

NMD participation is certified as a Practice Quality Improvement (PQI) projects toward American Board of Radiology Part IV Maintenance of Certification (MOC) credit.
