目的 :评价99TcmO4 与99Tcm_MIBI(甲氧基异丁基异腈 )核素显像对亚急性甲状腺炎的诊断价值。方法 :亚甲炎组35例 ,正常对照组31例 ,两组均进行 99TcmO4 与 99Tcm_MIBI甲状腺显像。甲状腺显像运用4分计分系统 :0～3分别表示严重减低、减低、正常、升高。结果 :亚甲炎组中33例 99Tcm_MIBI显像较 99TcmO4 显像图像质量改善、计分增加 ,正常对照组计分增加不明显。分别经秩和检验和t检验 ,亚甲炎组 99TcmO4 显像与 99Tcm_MIBI显像有统计学意义(P<0.01) ;99Tcm_MIBI亚甲炎组与正常对照组无统计学意义(P>0.05)。结论 :99TcmO4 与99Tcm_MIBI联合显像可提高亚甲炎的诊断符合率
Objective: To evaluate the diagnostic value of 99TcmO4 and 99Tcm_MIBI (methoxyisobutylisonitrile) nuclide imaging in the diagnosis of subacute thyroiditis. Methods: Thirty-five cases of hypothyroiditis and 31 cases of normal control group were performed 99TcmO4 and 99Tcm-MIBI thyroid imaging. Thyroid imaging using 4 points scoring system: 0 ~ 3, respectively, said serious reduction, reduction, normal, increased. Results: The image quality of 99Tcm_MIBI imaging in 99 cases of arthritis group was improved compared with that of 99TcmO4 imaging. The scoring increased and the score of normal control group increased obviously. The results of rank sum test and t test showed that 99TcmO4 imaging and 99Tcm_MIBI imaging were statistically significant (P <0.01). There was no significant difference between 99Tcm_MIBI methionitis group and normal control group (P> 0.05). Conclusion: The combination of 99TcmO4 and 99Tcm-MIBI can improve the diagnostic coincidence rate of
