摘　　要：目的探讨CT扫描测量甲状腺重量的准确性,为临床131I治疗甲亢测量甲状腺重量提供一种较准确的方法。方法采用SIEMENS SOMATOM Emotion 6层螺旋CT扫描系统,利用其体积测量功能,对71例确诊原发甲亢患者手术前后甲状腺重量分别进行测量,两者值相减并与实际切除重量对比。结果CT测量的甲状腺重量差平均值为(46.382±20.677),实际切除的甲状腺重量平均值为(45.689±20.994),CT测量的甲状腺重量之差与手术实际切除重量差异无显著性(P>0.05),两者有高度相关性(r=0.927,P<0.01)。结论 CT能准确测量甲状腺的重量,从而为临床131I治疗甲亢时的甲状腺测重提供一种既准确又简便的方法。Objective To access the accuracy of measuring thyroid weight by CT,and provide an accurate method for evaluate thyroid weight before131 I therapy. Methods The weight of thyroid of 71 cases with hyperthyroidism was measured by SIEMENS SOMATOM Emotion scanner system both at pre- and post-operation,compared their dispersion with the weight after it was cut off. Results The average weight of thyroid measured by CT was 46. 382 ± 20. 677,the average actualweight was 45. 689 ± 20. 994,there is no distinct difference between the calculated weight and actual weight（ P〉0. 05）,and there has a high correlation between them（ r = 0. 927,P〈0. 01）. Conclusions CT can determine thyroid weight accurately,so it can provide an accurate and handy method in determining the weight of thyroid for hyperthyroidism patient will be treated with131 I.
