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。
Objective To evaluate the quality of thyroid mass with 99mTc-MIBI imaging and to analyze the pathological results. Methods 168 cases of cervical mass, all patients underwent conventional sodium pertechnetate imaging, if not developed 99mTc-MIBI imaging. Results Where99mTc-MIBI imaging of the original mass of the site of the high degree of development was high metabolic (thermal nodules). 99mTc-MIBI imaging was associated with a higher incidence of cancers with high nodules (39,168 cases, 232%). Conclusion The 99mTc-MIBI imaging has a high accuracy in determining the nature of cervical nodules. Especially, the localization of 99mTc-MIBI is much higher than that of conventional imaging in the past.
