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.
ICE image
Intravenous iodinated contrast injection for computerized tomography is a commonly used diagnostic tool in nearly every radiology practice. IV contrast extravasation is a known complication of this method and is estimated to occur in up to 0.9% of exams. Although often without serious consequences, these extravasations can produce significant signs and symptoms, and occasionally long-term sequelae.

New registrations for the ICE registry are no longer being accepted.
IRR 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. The new registry is scheduled to be available early 2017.
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.
NOPR image
The National Oncology PET Registry (NOPR) is a collaboration of the American College of Radiology Imaging Network (ACRIN), the American College of Radiology (ACR), and the Academy of Molecular Imaging (AMI). Participation in this registry facilitates Medicare reimbursement for certain types of positron emission tomography (PET) scans.
PQRS image
The National Radiology Data Registry is approved as a Physician Quality Reporting System (PQRS) Qualified Clinical Data Registry (QCDR) by the Centers for Medicare and Medicaid Services (CMS). Radiologists may use the NRDR QCDR to meet PQRS participation requirements by reporting nine measures across three National Quality Strategy (NQS) domains, to include at least one outcome measure. Measures can be selected from a list of PQRS measures supported by the NRDR QCDR and/or “non-PQRS” measures across the NRDR databases (CTC, DIR, GRID, ICE and NMD) for a total of nine. The measure lists with associated NQS domains and measure type are available for selection in this NRDR PQRS module. For more information, click here.
