目的 比较诊断剂量与治疗剂量 1 31 I在甲状腺的摄取率 ,为临床 1 31 I治疗甲亢提供依据。方法 采用SPECT的感兴趣区法测定 10 8例弥漫性甲状腺肿伴甲亢患者服用 1 31 I后 4、6、2 4 h甲状腺 1 31 I摄取率 ,比较两种剂量甲状腺 1 31 I摄取率之间的关系。结果 诊断剂量和治疗剂量的 2 4 h甲状腺 1 31 I摄取率之间无统计学差异 (P>0 .0 5 )。结论 诊断剂量与治疗剂量的 2 4 h的甲状腺 1 31 I摄取率是一致的
Objective To compare the diagnostic dose with the therapeutic dose of 131 I in the thyroid uptake rate for the clinical 1 31 I provide the basis for the treatment of hyperthyroidism. Methods Thirty-one cases of diffuse goiter with hyperthyroidism were enrolled in this study. The prevalence of 131 I uptake in thyroid was measured at 4,6,2 4 h after taking 131 I, Relationship. Results There was no significant difference in the uptake rate of thyroid 131 I between the diagnostic dose and the therapeutic dose at 24 h (P> 0.05). Conclusion The diagnostic dose and the therapeutic dose of 24 h thyroid 131 I uptake rate are consistent
