摘　　要：对照研究核素显像和Ｂ超测算甲状腺重量的相关性，为临床提供较准确及简易的方法。３６３例甲亢病人１３１Ｉ治疗前分别进行γ显像和Ｂ超检查，以测算甲状腺体积（重量），其中６５例弥漫性甲状腺肿合并甲亢病人１３１Ｉ治疗后６个月重复两种检查。３６３例病人显像和Ｂ超测算甲状腺重量相关良好（ｒ＝０９３，Ｐ＜００１），总体上显像所得重量平均值大于Ｂ超值，腺体厚度是影响测算结果的主要因素；１３１Ｉ治疗后腺体厚度缩小最著，显像值大于Ｂ超值更明显。甲状腺重量测算在一定范围内两种方法可互相替代。１３１Ｉ治疗后，Ｂ超测定值为准。存在结节时，以显像为优。PURPOSE To observe the correlation between thyroid weights determined by scintigraphy and ultrasound METHODS Thyroid volume (weight) was determined by nuclear medicine scintigraphy and ultrasound in 363 hyperthyroidism patients before 131 I therpay Among them, 65 cases of diffuse goitre with thyroxicosis were studied again both by scintigraphy and ultrasound 6 months after therapy RESULTS A good correlation was observed between thyroid weights determined by scintigraphy and ultrasound (r=0 93, P<0 01) The average value determined by scintigraphy was more than that by ultrasound The main influencing factor was thyroid thickness CONCLUSIONS When thyroid weights were in fitting range, scintigraphy or ultrasound can be used either After 131 I therapy, the results of ultrasound were more accurate The scintigraphy could be selected when thyroid had nodules
