:

: The scientific guarantor of this publication is Dr. Rebecca Smith-Bindman.

: Dr. Smith-Bindman is a co-founder of Alara Imaging, Inc., a new company focused on improving the clinical and operational aspects of health systems, including collecting and reporting CT radiation dose and image quality as part of payer-led quality programs. Alara Imaging had no role in the study, and Dr. Smith-Bindman has not received funding from Alara Imaging. The other authors have no conflicts to disclose.

: Mr. Matthew Malekhedayat performed all statistical analyses for this study, with consultation from Mr. Philip Chu and Dr. Yifei Wang.

: The UCSF International CT Dose Registry (from which this work was derived) was approved by the UCSF Institutional Review Board with a waiver of informed consent for all subjects. The waiver was approved for three reasons: the attempt to contact subjects poses a greater risk than this study; the large number of records required makes it impracticable to contact all potential subjects; and the researchers do not know the identity of the study subjects and therefore cannot contact them.

: Institutional Review Board approval was obtained.

: There is no overlap with previous work.
