Abstract
-Author Affiliations
The number and specification of radionuclide examinations, administrated activity and effective doses were collected during 2011–13 for 4944 paediatric patients from 10 nuclear medicine (NM) departments of some Russian regions. The kidney examinations account for about 70 % of paediatric NM examinations in general hospitals. Diagnostics of all other organs contribute from 2 to 8 % each in the total number of paediatric examinations. Administrated activities of radiopharmaceuticals are approximately proportional to the child's age, and variations between different hospitals usually are within the factor of 3–4 and for some types of examination up to 10. The range of the effective dose due to paediatric NM examinations is roughly estimated as 2–6 mSv per examination, approximately the same as in adults. Some examinations (heart, thyroid, whole body) result in doses of younger children that are 2–3 times higher than the doses of adults. Effective doses in paediatric positron emission tomography (PET) diagnostics are in the range of 4–10 mSv per examination and are higher compared with the dose of adult patients. The application of combined radiodiagnostic technologies (single photon emission computer tomography with roentghen computer tomography [SPECT/CT] or PET with roetghen computer tomography [PET/CT]) increases the effective dose of patients by the factor of 1.5–2 for the skeleton or whole body examinations.
