Abstract:
Background: The purpose of this study is to evaluate the effective dose (ED) for computed
tomography (CT) examination in different age groups and medical exposure in pediatric imaging
centers in Tehran, Iran. Methods: Imaging data were collected from ۵۳۲ pediatric patients from four
age groups subjected to three prevalent procedures. National Cancer Institute CT (NCICT) software
was used to calculate the ED value. Results: The mean ED values were ۱.۶۰, ۴.۱۶, and ۱۰.۵۶ mSv
for patients’ procedures of head, chest, and abdomen–pelvis, respectively. This study showed a
significant difference of ED value among five pediatric medical imaging centers (P < ۰.۰۵). In head,
chest, and abdomen–pelvis exams, a reduction in ED was evident with decreasing patients’ age.
Conclusion: As there were significant differences among ED values in five pediatric medical imaging
centers, optimizing this value is necessary to decrease this variation. For head CT in infants and also
abdomen–pelvis, further reduction in radiation exposure is required.
