The American College of Radiology (ACR) is expanding its Lung Cancer Screening Registry, which will evolve into the Early Lung Cancer Detection Registry in late 2025.
The expansion will support diagnostic performance feedback on management of actionable incidental pulmonary nodules using current ACR Learning Network Recommendations Follow-Up Collaborative measures, the ACR said. These measures focus on the quality of radiology report recommendations and timely follow-up completion rates.
Incidental pulmonary nodules are the most common actionable incidental finding in radiology exams and have become more common as imaging resolution improves, yet an estimated 60% of patients with IPNs are lost to follow-up, the organization noted. The new Early Lung Cancer Detection Registry is hoped to help healthcare organizations improve management of incidental pulmonary nodules through diagnostic performance feedback and benchmarking, the ACR said.
The ACR received a $100,000 grant to expand the registry last year. More information can be found here.

The CT image is shown in the axial plane. The PMV is automatically extracted using the developed deep learning model and overlayed onto the lungs for visual clarity.](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/03/genkin.25LqljVF0y.jpg?auto=format%2Ccompress&crop=focalpoint&fit=crop&h=112&q=70&w=112)
