目的评价99m锝-甲氧基异丁基异腈(99mTc-MIBI)显像在甲状腺“冷、凉”结节性质鉴别中的价值。方法对72例经99mTcO4-显像发现为“凉”及“冷”结节患者做99mTc-MIBI显像,根据结节部位核素分布与周围组织核素分布比较,判断阳性、阴性。结果阳性26例,阴性46例。与手术后病理对照,准确率76.9%,假阳性率23.1%,假阴性率6%。结论 99mTc-MIBI显像在甲状腺“冷、凉”结节性质鉴别中有较大的价值。
Objective To evaluate the value of 99mTc-methoxy-isobutyl isonitrile (99mTc-MIBI) imaging in the identification of thyroid gland “cold and cool” nodules. Methods Totally 99m Tc-MIBI imaging was performed in 72 patients with “cold” and “cold” nodules detected by 99mTcO4-imaging. According to the distribution of radionuclide nodules and the distribution of surrounding tissue nuclide, the positive results were obtained. negative. The result was positive in 26 cases and negative in 46 cases. Compared with postoperative pathology, the accuracy was 76.9%, the false positive rate was 23.1%, and the false negative rate was 6%. Conclusion 99mTc-MIBI imaging is of great value in the differential diagnosis of thyroid nodules.
