Trends in Pediatric Imaging From 1997 to 2024 in an Integrated Health Care Setting.

From 2017 to 2024, cross-sectional imaging increased 50% (relative rate 1.46 [95% CI, 1.45-1.48]) from 79 (95% CI, 79-79) to 116 (95% CI, 115-117) examinations/1000 children associated with an average annual increase of 6.3% (95% CI, 5.0%-6.5%).

Average annual change in US use 2017-2024 was 3.0% (95% CI, -0.3% to 6.4%), reaching its peak use rate in 2024 of 49 (95% CI, 49-49) examinations/1000 children.

An estimated 8,880 future cancers in 2017 and 15,420 in 2024 in the United States may be attributable to CT use observed in this cohort.
