Abstract
BackgroundThis study aims to provide a reference for the diagnosis of iodine deficiency disorder by evaluating the normal thyroid iodine content by energy spectrum computed tomography (CT) and calculating the iodine content ratio of thyroid to sternocleidomastoid.MethodsThe thyroid glands of 226 patients were scanned by energy spectrum CT, and the images were analyzed using the GSI Viewer software. Based on the imaging findings, the iodine levels of the thyroid lobes as well as the bilateral sternocleidomastoids were evaluated, and their iodine content ratios were calculated.ResultsNo statistically significant difference was found in the thyroid iodine content between the left and right thyroid lobes (p > 0.05). However, there was a significant difference in the thyroid iodine content between men and women (p < 0.01). Additionally, the thyroid iodine content was found to decrease gradually with age. The iodine content ratio of thyroid to sternocleidomastoid was 96.6271 ± 33.2442.ConclusionGemstone energy spectrum CT can be used for the measurement of thyroid iodine content in the human body. It can play a significant role in the diagnosis of iodine deficiency disorder.

These values can be used to determine whether the thyroid dysfunction is caused by iodine deficiency or excess, which is clinically significant in the diagnosis of thyroid diseases [6]
It has been reported that excessive iodine intake as well as its deficiency can lead to thyroid dysfunction, which exhibits a U-shaped relationship with iodine intake [19, 20]
Summary
This study aims to provide a reference for the diagnosis of iodine deficiency disorder by evaluating the normal thyroid iodine content by energy spectrum computed tomography (CT) and calculating the iodine content ratio of thyroid to sternocleidomastoid. Iodine deficiency or excess iodine can cause thyroid dysfunction [1, 2], leading to abnormal iodine content in the thyroid tissues, which results in disorders of the thyroid and other organs of the body [3,4,5]. The iodine intake levels of the thyroid and in vivo storage concentrations can be evaluated by measurement of the iodine content of the thyroid tissue. These values can be used to determine whether the thyroid dysfunction is caused by iodine deficiency or excess, which is clinically significant in the diagnosis of thyroid diseases [6].
