Analysis of Computed Tomography Radiation Doses Used for Lung Cancer Screening Scans.

ABSTRACT:

Importance

The American College of Radiology (ACR) has recognized the importance of minimizing radiation doses used for lung cancer screening (LCS) computed tomography (CT). However, without standard protocols, doses could still be unnecessarily high, reducing screening margin of benefit.

Objective

To characterize LCS CT radiation doses and identify factors explaining variation.

Design, setting, and participants

We prospectively collected LCS examination dose metrics, from 2016 to 2017, at US institutions in the University of California, San Francisco International Dose Registry. Institution-level factors were collected through baseline survey. Mixed-effects linear and logistic regression models were estimated using forward variable selection. Results are presented as
