摘要：

目的 探讨核医学显像对甲状腺癌的诊断价值。方法 选择2013年3月至2016年3月我院收治的50例甲状腺结节患者，所有患者采取99Tcm-MIBI显像诊断和病理诊断，将两种结果进行分析比较。结果 本组50例甲状腺结节患者中99Tcm-MIBI显像阳性者24例(48.00%)、阴性26 例(52.00%);99Tcm-MIBI 显像诊断甲状腺癌9例(90.00%);甲状腺癌采用99Tcm-MIBI显像检查的阳性预测值为37.50%(9/24)，甲状腺良性病变99Tcm-MIBI显像检查阴性预测值为96.20%(25/26)。边界模糊、放射性浓聚区清除速度慢时，甲状腺癌采用99Tcm-MIBI显像的预测发生率为70.00%(7/10)。结论 采取核医学99Tcm-MIBI显像诊断甲状腺癌阳性预测值较低，易出现假阳性情况，可见单纯采用99Tcm-MIBI显像诊断甲状腺癌并不是非常理想的方案，建议采取多种方式联合检测以提高诊断准确率。

ABSTRACT: Objective To explore the diagnostic value of nuclear medicine imaging for thyroid caricinoma. Methods Fifty cases patients with thyroid nodule from March 2013 to March 2016 were selected and taken 99Tcm-MIBI maging diagnosis and pathological examination. The results of two methods were analyzed and compared. Results The positive imaging of thyroid nodule patients with 99Tcm-MIBI were 24 cases(48.00%), the negative imaging were 26 cases(52.00%), 9 cases (90.00%) were diagnosed to be thyroid carcinoma; the positive predictive value of thyroid caricinoma with 99Tcm-MIBI was 37.50%(9/24), and the negative predictive value of thyroid benign lesions was 96.20%(25/26); the predictive incidence rate of thyroid caricinoma with 99Tcm-MIBI was 70.00% (7/10) in fuzzy boundary and radioactive concentration area. Conclusion The positive predictive value of diagnosis for thyroid caricinoma with 99Tcm-MIBI is low, and it is easy to get false positives, so the diagnosis for thyroid carcinoma with 99Tcm-MIBI alone isn鸳t the optimal solution, the combined detection is suggested to take for improving the accuracy diagnostic rate.
