摘　　要：目的用超声检测正常胎儿甲状腺,并测量胎儿甲状腺的左右径及前后径,分析甲状腺的发育随孕周变化的规律。方法将胎龄为23~36周的237胎正常胎儿按照胎儿孕周分为7组,测量胎儿甲状腺的左右径及前后径,计算正常均值,并分析与孕周的相关性。结果胎儿甲状腺的左右径及前后径测值随胎龄增加而增大,与孕周呈显著正相关(P<0.05)。结论用超声对胎儿甲状腺进行观察、测量简易可行,可为甲状腺肿大胎儿的检出提供临床依据。Objective To measure fetal thyroid transverse and anteroposterior diameter by ultrasound and analy- sis the ehanges of thyroid development with gestational ages. Methods 237 normal fetus（gestational ages from 23 weeeks to 36 weeks） were divided into 7 groups. The diameter of fetal thyroid tranverse and anteroposterior was meas- ured and the normal average values were calculated. The correlation of fetal thyroid tranverse and anteroposterior di- ameter with the gestational ages was analyzed. Results The fetal thyroid tranverse and anteroposterior diameter was positively correlated with gestational age （P^0.05）. Conclusions With ultrasound, the measurent and observation on fetal thyroid is simple and feasible, which can provide clinical basis for the detection of fetal thyroid enlargement.
