Harness the Power of Collective Learning

Improving your practice’s performance — and patient care — starts with real-world, in-depth knowledge. Our National Radiology Data Registry (NRDR) delivers a wide range of data to guide improvement projects through benchmarking and identification of outliers on outcome or process-of-care measures.

Facility data contributed to the registries is made available to explore a wide range of questions about the practice of radiology and develop new areas for improvement.

NRDR differs from the ACR National Clinical Imaging Research Registry™ (ANCIRR) that collects images and clinical data from multiple practice settings. It enables researchers to address complex scientific questions and produce results applicable across various care settings, geographic locations and populations.
