目的 探讨多排螺旋CT在测量正常儿童甲状腺大小、体积的应用。 方法 前瞻性选取2017年6月~ 2019年9月重庆医科大学附属儿童医院放射科颈部CT检查的8、9、10、11岁等年龄段儿童240名，每个年龄组男、女儿童各30名；计算儿童体表面积，测量儿童两侧甲状腺前后径、内外径、上下径及体积；比较各个年龄段儿童甲状腺测量值，比较相同年龄段男、女儿童甲状腺测量值，比较相同年龄段儿童甲状腺左叶、右叶测量值，分析儿童甲状腺测量值和其影响因素之间关系。 结果 8 ~ 11岁年龄段儿童甲状腺体积右叶大于左叶（P<0.05）；8岁组儿童，甲状腺体积男性大于女性（P<0.05），其余组儿童，甲状腺体积女性大于男性（P<0.05）；8 ~ 11岁年龄段儿童甲状腺体积与体重、体质指数、体表面积呈正相关（P<0.05）。 结论 多排螺旋CT测量儿童甲状腺大小、体积，对儿童甲状腺疾病诊断治疗具有参考意义。
Abstract
Objective To explore the application of multi-slice spiral CT in measuring the size and volume of thyroid gland in normal children. Methods A total of 240 children aged 8，9，10，11 years old were prospectively selected from the department of Radiology, Children’s Hospital Affiliated to Chongqing Medical University from June 2017 to September 2019, including 30 boys and 30 girls in each age group. The body surface area of children was calculated, the anterior and posterior diameters, inner and outer diameters, the S-I diameters and the volumes of thyroid glands on both sides of children were measured. The thyroid measurement values of children at all ages, the thyroid measurement values of boys and girls at the same age, the thyroid measurement values of left lobe and right lobe of children at the same age were compared. The relationship between the thyroid measurement values of children and its influencing factors was analyzed. Results The thyroid volume in the right lobe was larger than that in the left lobe in children aged 8~11 years old groups (P<0.05). In the 8 years old group, the thyroid volume in male children was larger than that in female children (P<0.05). In other groups, the thyroid volume in female children was larger than that in male children (P<0.05). The thyroid volume was positively correlated with children's body weight, body mass index and body surface area in children aged 8~11 years old groups (P<0.05). Conclusions Multi-slice spiral CT can measure the size and volume of thyroid gland in children, which has clinical significance for the diagnosis and treatment of thyroid diseases in children.
