Inadvertent Thyroid Radiation During Computed Tomography of the Chest: A Retrospective Study

BACKGROUND፡ The thyroid, along with the breast, lung, and bone marrow, is among most radiosensitive organs. This study aims to assess rate of unnecessary radiation exposure thyroid gland in patients who had chest Computed Tomography (CT) at a large teaching hospital. 
 METHOD: Hospital-based retrospective cross-sectional on 1,306 underwent CT from July 2018 January 2019. Thyroid inclusion dose studies was evaluated. Data collected by evaluating scans Picture Archive Communication System (MedWeb).
 RESULT: Out 1306 patients, Chest intravenous iodinated contrast media used 95.4% scans. included 99.8% scans, out which 76.9% whole gland. Among previous 75.3% one scan 24.7% two DLP (Dose Length Product) mGycm lower females (360.33±32) compared males (426.45±378.4). lowest value observed pediatric age range 1-5 years 146.83, while highest those above 18 mean 418.31. CONCLUSION: majority unnecessarily include gland, sensitive organs for radiation-induced effects. Authors recommend optimized technique avoid future impacts.
