【摘要】 目的用99mTc-MIBI显像对甲状腺包块进行定性分析并与病理结果进行分析。方法颈部包块168例,全部病例均行常规高锝酸钠显像,若不显影,再行99mTc-MIBI显像。结果凡99mTc-MIBI显像原包块部位显影度增高者为高代谢性(热结节)。凡是冷结节而99mTc-MIBI显像为高代谢的癌变发生率更高(39168例,占232%)。结论99mTc-MIBI显像对颈部结节的性质确定具有较高的准确性,尤其是对甲癌的定位比过去单纯的常规显像的阳性率大大提高。更多还原

【Abstract】 SONG Bang-kun,CHEN Jian-wei,XU Yan-hong,et al.(1st People’s Hospital of Yunnan Province,Kunming 650032 China) Objective Combinning with pathological results, 99m Tc-MIBI imaging was adopted to qualitatively analyse cervical lumps.Methods After the cervical lumps of 167 cases were clinically touched,they were performed routinely by Na 99m TcO 4 imaging and their“cold node”were found.1～5 days after the imaging, 99m Tc-MIBI imaging was practiced to them.Results If the nodular image of 99m Tc-MIBI image was deeper than the image of Na 99m TcO 4 imaging,the node was called “high metabolism node”(hot node).If a node was a cold node (low function node)in routine imaging,but it was a high metabolism mnode in 99m Tc-MIBI imaging,the carcinoma rate of this node was higher than other nodes(38/158cases,counting for 23.3%). Conclusions The accurate rate of 99m Tc-MIBI imaging in differentiating malignant cervical lump from benign ones is rather high,especially for differentiating thyroid carcinoma.If a node is a “cold node”in routine Na 99m TcO 4 imaging but a high metabolism node in 99m Tc-MIBI imaging,the possibility of thyroidal carcinoma should be considered,and thyroidectomy should be adopted. 99m Tc-MIBI imaging of thyroid node is a good guide for its clinical treatment.更多还原
