Cumulative exposure to ionising radiation from diagnostic imaging tests: a 12-year follow-up population-based analysis in Spain.

ABSTRACT:

Objectives

To calculate each patient's cumulative radiation exposure and the recurrent tests during a 12-year study period, according to sex and age, in routine practice.

Design

Retrospective cohort study.

Setting

A general hospital with a catchment population of 224 751 people, in the Southeast of Spain.

Participants

Population belonged to the catchment area of that hospital in 2007. We collected all consecutive diagnostic imaging tests undergone by this population until 31 December 2018. We excluded: imaging tests that did not involve radiation exposure.

Main outcome measures

The cumulative effective dose and the recurrent imaging tests by sex and age at entry of study.

Results

Of the 224 751 people, 154 520 (68.8%) underwent an imaging test. Th
