Comparing practice performance to regional and national benchmarks is an important tool for improving the quality of patient care. The ACR National Radiology Data Registry (NRDR) will help your facility benchmark outcomes and process-of-care measures and develop quality improvement programs.

Registration Process and Fee Structure


New for 2014

NRDR PQRS Qualified Clinical Data Registry

The Centers for Medicare and Medicaid Services has approved the ACR National Radiology Data Registry as a Qualified Clinical Data Registry (QCDR) for the CMS Physician Quality Reporting System (PQRS) in the 2014 program year. Please click here for more information on using NRDR for PQRS reporting.


CT Colonography Registry

CT Colonography Registry

Designed to promote quality of care for patients undergoing CT colonography, the CTC registry provides evidence-based health outcomes and process data for decision-making purposes. The registry allows facilities to compare their results to regional and national benchmarks for quality improvement.


Dose Index Registry

Dose Index Registry

The DIR allows facilities to compare their CT dose indices to regional and national values. Institutions receive periodic feedback reports comparing their results by body part and exam type to aggregate results. This data will be used to establish national benchmarks for CT dose indices.


General Radiology Improvement Database

General Radiology Improvement Database

The GRID collects information about imaging facilities which is then aggregated to establish benchmarks for quality improvement. This allows facilities and physicians to compare turnaround times, patient wait times, incident rates and other process and outcome measures with other facilities and practices of similar size and type.


IV Contrast Extravasation Registry

IV Contrast Extravasation

ICE is a practice quality improvement project focused on CT IV contrast extravasation rates sponsored jointly by the ACR and the Society of Abdominal Radiology. This project collects data from institutions across the US to provide a meaningful way to compare practice performance in areas of quality and patient safety with national benchmarks.

National Mammography Database

National Mammography Database

The NMD leverages data that radiology practices are already collecting by providing comparative information for national and regional benchmarking. Participants receive semi-annual feedback reports that include important benchmark data such as cancer detection rates, positive predictive value rates and recall rates.
