中文摘要：

近年来，^124I PET／CT在DTC诊治中的应用引起了临床工作者越来越广泛的关注。结合cT精确的解剖学信息和PET高特异的功能学信息，^124I PET／CT可准确定位摄碘性病灶，探测非摄碘性病灶，从而更好地对DTC进行分期。此外，依赖其准确的剂量学评价结果，124I PET／CT剂量学评价可辅助制定DTC患者的治疗方案。笔者概述了^124I PET／CT在DTC诊治中的应用。

英文摘要：

In the past few years, there has been an increasing interest in the clinical applications of 124I PET/CT in patients with DTC. By combining anatomical and functional imaging, 124I PET/CT allows accurate localization of lesions with or without iodin avidity, thus contributes to better staging of DTC. Furthermore, 124 PET/CT may be used as a guiding tool in dosimetry measurements for the therapeutic management of patients with DTC. In this paper, we reviewed the studies of 124 IET/CT in clinical diagnosis and treatment of DTC.
