CT radiation exposure increases brain cancer risk in children - AuntMinnie

The findings suggest that it's important to way children's radiation vulnerability from CT, wrote a squad led by Prof. Michael Hauptmann, PhD, of Brandenburg Medical School successful Neuruppin, Germany.

"[Our] survey adds important grounds that vulnerability to [even] debased doses of radiation from immoderate root is associated with accrued crab risk," the radical noted.

CT is simply a invaluable diagnostic tool, but it imparts important radiation -- a information that is of peculiar interest for children. Despite initiatives specified arsenic ImageGently and guidance from the International Commission of Radiological Protection, galore CT exams whitethorn beryllium performed unnecessarily, and dose simplification measures aren't being utilized arsenic they could be, the authors wrote.

Hauptmann' and colleagues' probe took information from the World Health Organization's (WHO) International Agency for Research connected Cancer's EPI-CT study, which evaluates crab hazard from CT exams successful children and young adults. The survey included accusation from 658,752 patients, 9 European countries, and 276 hospitals. Participants had undergone astatine slightest 1 CT exam earlier the property of 22 betwixt 1977 and 2014, had nary erstwhile crab oregon benign encephalon tumor diagnosis, and were escaped of crab astatine slightest 5 years aft their archetypal CT exam.

The investigators calculated "excess comparative risk" of encephalon crab per 100 mGy of cumulative encephalon radiation dose, reconstructing organ doses utilizing humanities instrumentality settings and a thorough illustration of CT images. Primary result for the survey was archetypal reported encephalon crab 5 years aft an idiosyncratic had a archetypal CT exam.

During median follow-up of 5.6 years, 165 encephalon cancers were diagnosed. Mean cumulative radiation dose was 47.4 mGy among each survey participants and 76 mGy among those diagnosed with encephalon cancer. The authors recovered a important narration betwixt dose and encephalon cancer, with an excess comparative hazard per 100 mGy of 1.27 (with 1 arsenic reference).

The survey underscores the request for cautious information erstwhile it comes to CT imaging successful a pediatric population, according to Hauptmann and colleagues.

"[Our findings] stress the request to adhere to the basal radiological extortion principles successful medicine namely justification (procedures are due and comply with guidelines) and optimization (doses are arsenic debased arsenic reasonably achievable)," they concluded.
