ACR National Clinical Imaging Research Registry™ (ANCIRR)

The American College of Radiology® (ACR®) has brought together the full power of its world-class ACR Center for Research and Innovation (CRI) along with our ACR Informatics™ resources to launch the innovative ACR National Clinical Imaging Research Registry™ (ANCIRR).

The ANCIRR registries below, and those yet to launch, can collect images and clinical data from multiple practice settings — enabling researchers to address complex scientific questions and produce results applicable across various care settings, geographic locations and populations.

The ANCIRR differs from the National Radiology Data Registry (NRDR®), a radiology clinical quality improvement registry, which receives data from facilities to enable practice quality improvement through site feedback and benchmarking against peers.

Please review the ANCIRR frequently asked questions and bookmark this page and visit the individual ANCIRR registry sites below for more information.

ACT-RADS Research Registry™ (ACTRR)

The Actionable Imaging Findings Research Registry, involving three large U.S. health systems, seeks to aid development of a global standardized follow-up recommendation system for actionable imaging findings (ACT-RADS™) in abdominopelvic ultrasound (US), computed tomography (CT) and magnetic resonance imaging (MRI) exams.

COVID-19 Imaging Research Registry™ (CIRR)

The CIRR will advance understanding, prevention and treatment of COVID-19. CIRR sites will contribute demographic information, clinical signs and symptoms data, imaging exams, laboratory test data and outcomes to be used for educational purposes, AI algorithm development and research studies.

TI-RADS Research Registry™ (TIRR)

ACR Thyroid Imaging, Reporting and Data System (TI-RADS™) Research Registry will compare ACR TI-RADS to other thyroid ultrasound risk stratification systems with the aim to reduce unnecessary thyroid biopsies while capturing clinically significant malignancies.

Medical Imaging and Data Resource Center (MIDRC)

The MIDRC is a multi-institutional initiative to accelerate machine learning innovation through data sharing for rapid and flexible collection, analysis and dissemination of imaging and associated clinical data by providing researchers with unparalleled resources in the fight against COVID-19.

The ACR CRI is the imaging coordinator for the National Heart, Lung, and Blood Institute (NHLBI) multicenter COVID-19 Observational Study (CORAL) which will link images with clinical data. CORAL will inform epidemiology and resource utilization via a registry; a detailed cohort, including a bio-specimen collection correlated with clinical phenotyping and outcomes; and a health system assessment.

SCCM Viral Infection and Respiratory Illness Universal Study (VIRUS) COVID-19 Registry

The ACR CRI is the imaging repository for the Society of Critical Care Medicine (SCCM) Discovery Viral Infection and Respiratory Illness Universal Study (VIRUS) COVID-19 Registry. The VIRUS study aims to create a real-time registry of ICU and hospital care patterns to evaluate safety and observational effectiveness of COVID-19 practices.
