Chest X-ray imaging is the most common X-ray imaging method for diagnosing coronavirus disease. The thyroid gland is one of the most radiation-sensitive organs of the body, particularly in infants and children. Therefore, it must be protected during chest X-ray imaging. Yet, because it has benefits and drawbacks, using a thyroid shield as protection during chest X-ray imaging is still up for debate.Therefore, this study aims to clarify the need for using a protective thyroid shield during chest X-ray imaging. This study was performed using different dosimeters (silica beads as a thermoluminescent dosimeter and an optically stimulated luminance dosimeter) embedded in an adult male ATOM dosimetric phantom. The phantom was irradiated using a portable X-ray machine with and without thyroid shielding. The dosimeter readings indicated that a thyroid shield reduced the radiation dose to the thyroid gland by 69% ± 18% without degrading the obtained radiograph. The use of a protective thyroid shield during chest X-ray imaging is recommended because its benefits outweigh the risks.
胸部X线成像是诊断冠状病毒病最常用的X线成像方法。甲状腺是人体对辐射最敏感的器官之一，尤其是在婴幼儿和儿童中。因此，在胸部X线成像过程中必须对其加以保护。然而，由于使用甲状腺防护盾有其利弊，在胸部X线成像时使用甲状腺防护盾作为防护措施仍存在争议。因此，本研究旨在阐明在胸部X线成像时使用保护性甲状腺防护盾的必要性。本研究使用嵌入成年男性ATOM剂量学体模中的不同剂量计（作为热释光剂量计的硅珠和光激励发光剂量计）进行。使用便携式X线机对体模进行照射，照射时使用和不使用甲状腺防护装置。剂量计读数表明，甲状腺防护盾可使甲状腺所受辐射剂量降低69%±18%，且不会降低所获得的X线片质量。建议在胸部X线成像时使用保护性甲状腺防护盾，因为其益处大于风险。
