A systematic review of radiation dose to the eye lens from pediatric brain computed tomography scans.

ABSTRACT:

Background

With the increasing use of pediatric brain computed tomography (CT) and the International Commission on Radiological Protection's revised threshold for radiation-induced lens opacities, concerns have grown regarding cumulative radiation exposure to the eye lens.

Objective

This review examines the magnitude of lens doses reported in pediatric brain CT and the methodologies used to estimate these doses.

Methods

A systematic literature search of MedLine, Embase, and PubMed (2012-2024) identified 18 eligible studies, including direct patient measurements, phantom-based experiments, and computational modeling.

Results

Reported lens doses varied widely across studies. Software-based tools generally estimate higher doses than those measured directly on pati
