由于临床扪诊和同位素扫描对甲状腺大小的估计不够准确,作者采用灰度超声显象仪(Grey-Sca1e Ultrasound Images)测量20个甲状腺肿大病人的甲状腺,并将所得结果和们诊、甲状腺扫描及手术标本作了对比。结果发现,超声波所得数值和手术结果及们诊结果很接近,而和扫描所得结果差距较大。并进一步发现临床扪诊结果在甲状腺小于40ml者比较准确,在40ml以上时扪诊结果往往比手术所得数值为小。同位素扫描对甲状腺大小估价并不可靠。所以,超声波在甲状腺的应用不仅在于区别囊肿和实质性肿块、鉴别迅速增大的甲状腺肿块是由出血抑或恶性肿瘤所致
Because clinical palpation and isotope scans do not accurately estimate the size of the thyroid, the authors measured the thyroid gland in 20 goiter patients using a gray-scale ultrasound (Gray-Sca1e Ultrasound Images) and compared the results with those of a thyroid scan And surgical specimens for comparison. The results showed that the value of ultrasound and surgical results and consultation results are very close, and the results of the larger difference between the scan. And further found that clinical palpation results in the thyroid less than 40ml more accurate, more than 40ml palpation results are often smaller than the value of the surgery. Isthmus scanning is not reliable for evaluating thyroid size. Therefore, the application of ultrasound in the thyroid gland is not only to distinguish between cysts and substantial lumps, the identification of rapidly increasing thyroid mass is caused by hemorrhage or malignancy
