摘要
目的：探讨Ｘ－ＣＴ扫描计算甲亢患者甲状腺重量，为临床１３１Ｉ治疗甲亢计算甲状腺重量提供较准确的方法。方法：采用东芝ＴＣＴ－３００／ＥＺ全身ＣＴ扫描系统，４９例甲亢病人１３１Ｉ治疗前行甲状腺扫描，计算甲状腺体积（重量）。结果：４９例甲亢病人ＣＴ扫描计算的甲状腺重量为５１．５９９±２９．２０（１６．１６～１２６．８４）ｇ，与Ｂ超检查结果［４５．６３５±２３．０２（１４．９８～１０１．２９）ｇ］进行比较，ＣＴ测值要大于Ｂ超测值，但差异无显著性（Ｐ＞０．０５），两者间相关性良好（ｒ＝０．８８６，Ｐ＜０．００１）。结论：ＣＴ能够准确计算甲状腺体积（重量）。
Purpose:To evaluate the appproach to determination of thyroid volume by X-CT. Methods:Thyroid volume (weight)was determined by X-CT in 49 cases with hyperthyroidism before^(131) I therapy.Results:The average weight was 51.599±29.20(16.16～126.84)grams by X-CT and 45.635±23.02(14.98～101.29) grams by ultrasound,respectively.There was a good correlation between thyroid weights estimated by X-CT and ultrasound (r=0.886,P<0.001).The average weight by X-CT was more than that by altrasound,but no significant difference (P>0.05).Conclusions:Thyroid volume (weight) could be determined by X-CT easily and accurately for^(131)I therapy of hyperthyroidism.
