Graves病和桥本甲状腺炎患者甲状腺CT值的变化及临床意义

目的探讨Graves病和桥本甲状腺炎（HT）患者的甲状腺CT值变化及其临床意义。方法选取Graves病患者112例（GD组）、HT患者54例（HT组）、健康体检者36名（NC组），分别检测其甲状腺CT值。结果GD组左侧甲状腺CT值为（70．53±15．44）Hu，右侧为（70．50±16．01）Hu；HT组左侧甲状腺CT值为（53．77±4．88）Hu，右侧为（52．38±6．67）Hu；NC组左侧和右侧甲状腺CT值分别为（99．66±9．80）、（100．77±10．66）Hu。GD组和HT组的甲状腺CT值均较NC组低（P均〈0．01），并且HT组的甲状腺CT值较GD组减低更明显（P〈0．01）。结论（1）Graves病和HT患者的甲状腺CT值明显低于健康对照者，并且HT患者的甲状腺cT值较Graves病患者减低更明显；（2）甲状腺CT值可以作为一种早期、无创性地诊断Graves病和HT的辅助检测指标之一。

CT value characteristics and significance of Graves disease and Hashimoto＇s thyroiditis

Objective To investigate the change and clinical significance of thyroid CT value in patients with Graves disease and Hashimoto＇s thyroiditis （HT）. Methods One hundred and twelve Graves patients（ GD group）, 54 HT patients （ HT group ） and 36 healthy people （ NC group ） were selected as our subjects. Computed tomography （CT） value of thyroid were measured. Results The CT value of the left thyroid gland was （70. 53 ±15.44） Hu in GD group ,while （70. 50 ± 16. 01 ） Hu at the fight side. In HT group ,the CT value of the left thyroid gland was （53.77 ±4. 88） Hu,and （52. 38 ±6. 67） Hu at the fight side. The CT value of the left and fight sides was （99. 66 ±9. 80） Hu and （ 100. 77 ± 10. 66） Hu in the NC group respectively. The CT value of GD and HT group were lower than that of the NC group （ P 〈 0. 01 ）, and the CT value of the HT group lower than that of the GD group more significant （P 〈 0.01 ）. Conclusion （ 1 ） The CT value of the GD group and the HT group are significantly lower than the NC group and the CT value of the HT group reduces more apparently than that of the GD group. （2） CT values can be used as an early, non-invasive diagnosis of GD and HT secondary indexes.
