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.
![Axial images from unenhanced calcium score cardiac CT (left) and curved planar reformation images from CT angiography (right) show that higher long-term exposure to air pollution is associated with greater coronary artery calcium and more obstructive coronary artery disease (CAD).

Bottom row: Images in a 57-year-old female patient with lower 10-year mean ambient air pollution exposure (6.3 μg/m3 for PM2.5 and 4.6 ppb for NO2) with no CAD (CACS = 0 and no obstructive stenosis).](https://img.auntminnie.com/mindful/smg/workspaces/default/uploads/2026/06/hanneman.r6SMLzkezo.png?auto=format%2Ccompress&dpr=2&fit=crop&h=167&q=70&w=250)
