Abstract

Background: The normal reference values for the thyroid uptake of radioactive iodine and Tc-99m pertechnetate in euthyroid patients vary by geographical location as well as the amount of iodine intake in the diet. The present study examines the normal reference values for thyroid uptake of Tc-99m pertechnetate in the North of Iran.

Methods: The participants of this study were 64 patients (all over 20 years of age) who had referred to the Nuclear Medicine Center of the Shahid Beheshti Hospital for thyroid scan over the period between March 2018 and May 2020. It is worth mentioning that relying on laboratory test results, only patients with normal thyroid function were included in this cross-sectional study.

Results: The median, the 5^th and 95^th percentiles and thyroid uptake range of 99mTc-pertechnetate in euthyroid patients were 0.9, 0.6 to 1.8% and 0.54 - 1.80%, respectively.

Conclusion: The percentage of uptake in the thyroid gland in each geographical area varies based on race and diet content, so it is necessary to determine the percentage of uptake in each specific region and even check it periodically.

伊朗北部人群甲状腺摄取 Tc-99m 过硫酸盐的正常参考值：单中心经验。

背景：甲状腺摄取放射性碘和Tc-99m过硫酸盐的正常参考值因地理位置和饮食中碘摄入量的不同而异。本研究探讨了伊朗北部地区甲状腺摄取 Tc-99m 过硫酸盐的正常参考值：本研究的参与者为 2018 年 3 月至 2020 年 5 月期间转诊至沙希德-贝赫什提医院核医学中心进行甲状腺扫描的 64 名患者（均超过 20 岁）。值得一提的是，根据实验室检测结果，只有甲状腺功能正常的患者才被纳入这项横断面研究：99m锝-pertechnetate在甲状腺功能正常患者中的中位数、第5百分位数和第95百分位数以及甲状腺摄取范围分别为0.9%、0.6%至1.8%和0.54%至1.80%：每个地区的甲状腺摄取比例因种族和饮食内容而异，因此有必要确定每个特定地区的摄取比例，甚至定期检查。
