Journal of Research in Medical Sciences, 05/18/2012
Adibi A et al. – In this study, there was no correlation between occupational chronic exposure to a low dose of radiation and the risk of developing thyroid nodules.Methods
- In this case control study the prevalence of thyroid nodules in radiation exposed workers was determined by ultrasonography which was performed by a radiologist.
- The results were compared with the results of another study among the adult population of Isfahan city which were selected by Cluster – random sampling method.
- The two studied groups were matched according to sex and age.
- The studied population in case and control groups was 124 and 471 respectively.
- The prevalence of thyroid nodule in the case and control groups was 22.6% and 24.6% respectively (p > 0.05).
- Thyroid nodule was more prevalent in females in the control group but there was no difference between the females and males of the case group (p > 0.05).
- The number of thyroid nodules (single or multiple) and calcification were not different for the two groups (p > 0.05).
- Moreover, the echo pattern of thyroid nodules for hypoechogenicity was not different in the two groups (p > 0.05).
