The ACR and NRDR continually look for additional areas where a clinical quality registry would support quality improvement efforts in radiology and improved patient care. When new topics or focus areas are identified, we pilot test the concepts, processes and functionality required with a small number of test sites before opening a new registry for general participation. However, you may see the pilot registries in the NRDR applications page, and while participation is limited, you may contact us for more information at nrdrsupport.acr.org.
