We categorized individuals who had a CT (computed tomography) or CAT (computerized axial tomography) scan for LCS within the past year as having a recommended LCS. The facility list was compiled from the American College of Radiology-LCS Registry accessed in February 2025. The density of LCS facilities, defined as the number of facilities per 100,000 estimated at-risk populations, was employed to account for the varying screening-recommended population sizes in each state.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>\n                      Vermont had the fewest absolute number of facilities (9), while Florida had the most (669). However, Maine had the lowest LCS facility density (13.3), while D.C. had the highest (65.7) per 100,000 at-risk populations.
