目的：探讨甲状腺锥体叶显像的临床价值。材料和方法：常规肘静脉注射９９ｍＴｃＯ－４后３０分钟甲状腺显像，对２６０例甲状腺机能亢进症患者和２４３例非甲亢对照组患者行甲状腺显像，观察甲状腺锥体叶的出现情况。结果：２６０例甲亢患者中７８例锥体叶阳性，２４３例对照组中８例锥体叶阳性，两者差异有显著性（Ｐ＜００１），锥体叶阳性对甲亢诊断的敏感性为３００％，特异性为９６６％。锥体叶可位于峡部或一叶上方，多呈舌状，放射性分布略低于左右叶，大小不等。甲亢术后原有锥体叶可长大。结论：甲状腺锥体叶显像有助于甲亢的临床诊断。
Objective: To investigate the clinical value of thyroid cone imaging. Materials and Methods Thyroid imaging was performed 30 minutes after conventional intravenous injection of 99mTcO-4. Thyroid imaging was performed in 260 patients with hyperthyroidism and 243 non-hyperthyroid patients. The appearance of thyroid pyramidal lobes was observed. Results: Among 260 patients with hyperthyroidism, 78 cases were positive for pyramidal lobes and 8 cases were positive for pyramidal lobes in 243 cases. There was a significant difference between the two groups (P <001). The sensitivity of cones lobes to the diagnosis of hyperthyroidism 30 0%, specificity 96 6%. Cone leaves can be located in the isthmus or a leaf above, mostly tongue-like, radioactive distribution slightly lower than the left and right leaves, sizes. After the original hyperthyroidism cone can grow up. CONCLUSION: Thyroid cone imaging is helpful for the clinical diagnosis of hyperthyroidism.
