摘要
１２６例甲状腺结节患者进行了甲状腺静态及“三相”动态显像检查。主要评价指标有结节血流与摄９９ｍ锝功能及甲状腺／唾液腺摄９９ｍ锝比值。结果表明：６４．３％的癌性结节为“冷结节”，而腺瘤以“凉结节”居多（４７．６％）；甲状腺“冷、凉结节”中甲癌的发生几率分别为４９．３％与２９．３％，二者有显著性差异（Ｐ＝０．０２０５）。甲癌患者甲状腺摄碘功能或甲／唾比值下降的发生率较甲瘤患者也明显增高（Ｐ＝０．０３１２）。动态显像与Ｂ超结果比较，两者对甲状腺癌的鉴别诊断准确性分别为８５．７％与７１．４％，但差异无显著性（Ｐ＝０．１１０６）。上述结果提示：甲状腺显像是甲状腺血流、功能及结节性质判断的重要检测手段。
Thyroid static and dynamic imaging were performed in 126 patients with palpable mass. Main evaluating indeces included blood flow and function of nodules, as well as ￣(99m)TcO_-￣4 ingestion ratio of thyroid to salivary gland. Results showed that cold nodule accounted for 64. 3% of thyroid carcinoma. 47. 6% thyroid adenoma was cool nodule. The rate of suffering from thyroid cancer in cold and cool nodules was 49. 3% and 29. 3%, respectively(p=0. 0205). Dynamic imaging compared with B ultrosound, there was no significant difference in differentiating benign and malignant nodules, whose diagnosis accuracy were 85. 7% and 71. 4 respectively. The results indicate thyroid imaging is a significant method of appreciating thyroid blood flow, function and nodule quality, having good clinical value.
