A paper
by Nordenskjold et al published in Radiology
found that exposure to radiation from computed tomography of the head does not
increase the risk of developing a meningioma.
The
authors collected data from a cohort of 26 370 subjects from a radiology
archive of CT examinations of the head performed from 1973 through 1992. For
comparison, an age- and sex-matched cohort of 96 940 subjects who were not
exposed to CT (unexposed cohort) was gathered.
Comparison of exposed and unexposed cohorts no
statistically significant increase in the risk of meningioma was found among
patients who were exposed to ionizing radiation from CT of the head compared to
the unexposed control individuals.
