Abstract

Background and Aim: CT SCAN as a medical imaging modality delivers high RADIATION DOSE to the patients. Since eye and thyroid are two radiosensitive organs in this study, those effective doses were evaluated in brain CT SCAN. Using TLD as dosimeter.Materials and Methods: This cross-sectional study was carried out in three selective hospitals in Rasht in September and October in year 2016.TLD was used as personal dosimeter. To measure the effective dose, TLDs were put on the patient’s eyes and thyroid and the mean effective dose was evaluated in brain CT SCAN. Results were analytical using SPSS software and Anova (P<0.05).Results: The mean effective doses of eyes and thyroid in three hospitals with codes of H1, H2 and H3 were obtained as 2.66±2.04 mSv and 0.03±0.009 mSv, 1.80±1.11 mSv and 0.03±0.02 mSv, 1.94±0.95 mSv, 0.04±0.01 mSv, respectively. We found significant differences between effective doses of the eyes and thyroid in the three hospitals (p<0.05). Despite the difference in effective doses between right and left sides of eyes and thyroid, we didn’t find any other significant differences.Conclusion: The most important factor affecting patient RADIATION DOSE is the way CT SCAN examination is performed.
