|EPI-CT is a multinational cohort study of children and young adults who have undergone at least one computed tomography (CT) scan before the age of 22 years. It comprises three main parts: 1) an epidemiological cohort study assessing cancer effects of radiation exposure from CT; 2) a dosimetry system to evaluate individual doses and related uncertainty, and supporting dose reduction and optimisa on strategies; 3) a pilot study to evaluate the feasibility of applying diferent biomarkers of hypersensitivity in young patients exposed to low doses from CT.
International cohort comprising 1,163,571 patients from BE, DK, FR, DE, NL, NO, ES, SE and GB, who have undergone CT examination.
- age at exposure: from 0 to 22 years
- mean age at the first examination: 10 years,
-mean age at the end of cur- rent follow-up: 20 years
- follow-up period varies by country and ranges from 1973 to 2015
-Individual organ doses due to external X-ray irradiation, including uncertainty analy-sis;
- cancer incidence;
-vital status (except in Ger-many and partially in FR; -socioeconomic status availa-ble in BE, FR, NL, ES and GB -cancer predisposing syndromes available in FR, NL and NO.
