In comparison to findings from a similar study in 2014, the national volume computed tomography (CT) dose index (CTDLvol) declined by 9.3 percent, according to newly published research involving 5 million CT exams for over 2.8 million adults in 2025.

Researchers found that non-contrast head CT exams, head and neck CT exams and spine CT imaging increased by 33 percent, 76.9 percent and 52.9 percent, respectively, per 1,000 emergency department encounters over the last decade.
