Projected Lifetime Cancer Risks From Current Computed Tomography Imaging.

ABSTRACT:

Importance

Approximately 93 million computed tomography (CT) examinations are performed on 62 million patients annually in the United States, and ionizing radiation from CT is a known carcinogen.

Objective

To project the number of future lifetime cancers in the US population associated with CT imaging in 2023.

Design, setting, and participants

This risk model used a multicenter sample of CT examinations prospectively assembled between January 2018 and December 2020 from the University of California San Francisco International CT Dose Registry. Data analysis was conducted from October 2023 to October 2024.

Main outcomes and measures

Distributions of CT examinations and associated organ-specific radiation doses were estimated by patient age, sex, and CT category
