Estimates of the number of patients with high cumulative doses through recurrent CT exams in 35 OECD countries

While acknowledging the immensely useful role computed tomography (CT) plays in diagnosis and management of patients, attention has frequently been drawn to radiation exposure of patients. This has resulted in lowering the patient radiation doses in large parts of the world both at the per exam level and the collective dose [1 –4]. A recent study reported that low-doseCThad no effect on humanDNAwhereas in the same setting,DNAdouble-strand breaks and chromosome aberrations were shown to increase after standard-doseCT [5].
