分化型甲状腺癌腹盆部^131Ⅰ显像假阳性分析

Analysis of differentiated thyroid cancer false-positive uptake in abdominal cavity and pelvic cavity on radioiodine whole-body scan

全身^131Ⅰ显像时，除了甲状腺组织、分化型甲状腺癌（DTC）转移及复发灶显影外，非甲状腺组织来源的假阳性病变也常不同程度地摄取^131Ⅰ而显影。探讨DTC患者腹盆部非甲状腺组织来源的假阳性病变摄取^131Ⅰ的不同原因，分析其可能存在的病变信息，可以给临床诊疗提供必要的帮助，笔者就有关腹盆部^131Ⅰ显像假阳性研究进行综述。

When it comes to ^131Ⅰ radioiodine whole-body scan, normal thyroid tissue and differentiated thyroid cancer（DTC） can uptake radioiodine, so does the non-thyroid tissue to some extent. The understanding of the possible explanations for the abnormal radioiodine uptake in the abdominal cavity and pelvic cavity tissue on ^131Ⅰ radioiodine whole-body scan is of great importance to clinical diagnosis. The relevant reports about this field are reviewed.
