高频彩色多普勒超声在甲状腺疾病诊断中的应用

Application of high frequency color Doppler ultrasound in diagnosis of thyroid diseases

目的应用高频彩色多普勒超声（彩超）对甲状腺疾病发病率进行分析。方法应用高频彩超对2012年10月1日至2014年12月30日在该院健康体检的8 733人进行甲状腺超声检查,受检者年龄为20~85岁,分3个年龄段（20~45、〉45~60、〉60~85岁）检查甲状腺疾病的发病率,重点检查甲状腺结节和甲状腺癌的发病率。结果甲状腺疾病发病率为36.70%（男性30.98%、女性42.45%）,其中甲状腺结节的发病率为29.46%（男性25.84%、女性33.10%）,其他甲状腺疾病发病率为7.24%（男性5.14%、女性9.35%）。不同年龄段女性甲状腺结节发病率高于男性,且随年龄增长发病率增加,差异均有统计学意义（P〈0.01）。高频彩超提示警惕甲状腺癌者56例,随访45例行手术（39例经病理组织检查确诊为甲状腺癌,6例是良性结块）,11例仍定期复查中,病理诊断提示符合率为86.67%（男性82.35%、女性89.29%）。结论高频彩超检查可对甲状腺癌的早期诊断提供依据。

Objective To analyze the prevalence rate of thyroid diseases by using the high frequency color Doppler ultrasonography. Methods The thyroid ultrasound examination by using the high frequency color Doppler ultrasound was performed among the healthy physical examination of 8 733 respondents in our hospital from October 1,2012 to December30,2014,the subjects aged 20-85 years old,and were divided into 3 age groups of 20-45, 45-60, 60-85 years old. The incidence rate of thyroid diseases was examined,which was concentrated at the incidence rates of thyroid nodule and thyroid cancer. Results The prevalence rate of thyroid diseases was 36.70%（male 30.98%,female 42.45%）,in which the incidence rate of thyroid nodule was 29.46%（male 25.84%,female 33.10%）,which of other thyroid diseases was 7.24%（male 5.14%,female9.35%）. The incidence rate of thyroid nodule in different age periods of females was higher than that in males,moreover with the age increase,the incidence rate was elevated,the difference was statistically significant（P〈0.01）. Alerting thyroid cancer by the high frequency color Doppler ultrasound was in 56 cases,among them,45 cases of follow up were performed operation（39 cases were diagnosed as thyroid cancer by pathological tissue examination,6 cases were benign lumps）,11 cases were still followed up at regular interval. The pathological diagnosis indicated that the coincidence rate was 86.67%（male 82.35%,female 89.29%）.Conclusion The high frequency color Doppler ultrasound can provide the evidence for early diagnosis of thyroid cancer.
