摘　　要：目的探讨甲状腺彩色多普勒超声检查在医学放射工作人员职业健康监护中的应用价值。方法采用ALOKASSD-4000彩色多普勒超声诊断仪，对134名医学放射工作人员（观察组）及68名非放射工作人员（对照组）进行甲状腺彩超检查，并对检查结果进行比较。结果观察组甲状腺左右两叶前后径和峡部前后径均大于对照组，差异有统计学意义（P〈0．01）。观察组右侧甲状腺上动脉内径大于对照组，差异有统计学意义（P〈0．05）。观察组右侧甲状腺上动脉收缩期峰值血流速度大于对照组，差异有统计学意义（P〈0．05）。观察组甲状腺结节和淋巴结的检出率（18．7％和6．7％）均高于对照组（13．2％和1．5％），但差异无统计学意义（P〉0．05）。医学放射工作人员个人受照射剂量在0．14-1．67mSv/a之间，属于低剂量接触电离辐射。结论甲状腺彩色多普勒超声检查能检出长期接触低剂量电离辐射的医学放射工作人员甲状腺的早期变化。Objective To explore the value of color doppler ultrasound examination of thyroid in occupational health care of radiation-exposed physicians. Methods One hundred and thirty-four radiation- exposed physicians （observation group ） and sixty-eight non-radiation-exposed physicians （control group） received color doppler ultrasound examination of thyroid using ALOKA SSD-4000 color doppler ultrasonic diagnostic apparatus, and the results were compared between the two groups. Results The anteroposterior diameters of the left lobe, right lobe, and isthmus of the thyroid in the observation group were significantly larger than those in the control group （P〈0.01 ）. Compared with the control group, the observation group had significantly larger internal diameters and peak blood flow velocities during systole of the right superior thyroid artery （P〈0.05, P〈0.05 ）. There were no significant differences in detection rates of thyroid nodules and lymph nodes between the observation group and the control group （ 18.7% vs 13.2%, P〉0.05; 6.7% vs 1.5%, P〉0.05）. The radiation-exposed physicians were exposed to low-dose ionizing radiation with a dose between 0.14 and 1.67 mSv/a. Conclusion The color doppler ultrasound examination of the thyroid can detect early changes in the thyroid of radiationexposed physicians exposed to long-term and low-dose ionizing radiation.
