NRDR image
The National Radiology Data Registry is a data warehouse for the registries listed below. The primary purpose of NRDR is to aid facilities with their quality improvement programs and efforts to improve patient care by comparing facility data to that of their region and the nation. A practice or facility may choose to participate in any or all registries as appropriate for their practice. When a facility joins more than one registry, the warehouse allows information to be shared across registries within the facility.
CTC image
The CT Colonography Registry collects measures critical to evaluating CT colonography procedures. Data collected in this registry will contribute to the evaluation of colonography as an alternative to colonoscopy.
DIR image
The Dose Index Registry (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.
GRID image
The General Radiology Improvement Database (GRID) collects information about imaging facilities which is then aggregated to establish benchmarks for quality improvement. It allows facilities and physicians to compare turnaround times, patient wait times, patient satisfaction and many other process and outcome measures with other facilities and practices of similar size and type. For physicians participating in CMS’s Physician Quality Reporting Initiative, GRID provides a means of comparing results of the various imaging measures included in the initiative.
IR image
The new national quality registry for interventional radiology, the Interventional Radiology Registry, led by the Society of Interventional Radiology and the American College of Radiology, is designed to promote quality of care for patients undergoing interventional radiology procedures.
LCSR image
The ACR Lung Cancer Screening Registry™ is approved by the Centers for Medicare and Medicaid Services (CMS) to enable providers to meet quality reporting requirements to receive Medicare CT lung cancer screening payment. It will monitor physician and facility performance quality and provide comparisons and develop benchmarks.
NMD image
The National Mammography Database (NMD) leverages data that radiology practices are already collecting under federal mandate by providing them with comparative information for national and regional benchmarking. Participants receive semi-annual feedback reports that include important benchmark data such as true positive rates, positive predictive value rates and recall rates.
PQRS image
The ACR National Radiology Data Registry (NRDR) has been approved as a Qualified Clinical Data Registry (QCDR) for the CMS Merit-Based Incentive Payment System (MIPS). Radiologists may use the NRDR QCDR to meet MIPS participation requirements. By using the QCDR to participate in the MIPS program, radiologists can avoid a negative payment adjustment for not reporting and potentially earn an incentive. ACR will submit physician and/or group practice quality measure data, improvement activities and advancing care information measure data to CMS. For more information visit
The CDS R-SCAN Registry, now in pilot phase, is the newest registry under the umbrella of the American College of Radiology’s National Radiology Data Registry. The CDS R-SCAN Registry provides access to a subset of a facility’s imaging clinical decision support (CDS) data. Currently, participation is available for facilities that have CareSelect™ Imaging/ACR Select provided by the National Decision Support Company (NDSC).
