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
-
摘要: 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。Abstract: 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 I-131 radioiodine whole-body scan is of great importance to clinical diagnosis. The relevant reports about this field are reviewed.
