To determine strain index (SI) values at various locations in the pancreas and to investigate the relationship between age, gender, body weight, height, body mass index (BMI), and elasticity values of the pancreas in healthy children.
MATERIAL/METHODS: This cross-sectional trial was performed in 147 healthy children who underwent transabdominal ultrasonography for strain elastography of the pancreas. A convex, 3.5-5-MHz probe was used to obtain the images. Baseline descriptive data including age (months), body weight (kg), height (cm), and BMI (kg/m2) were noted. Strain index values were calculated for the head, body, and tail of the pancreas, and a mean value was obtained. The relationship between demographic variables and SI values was assessed. Correlation between variables with normal distribution was evaluated with Pearson's correlation coefficient and Spearman's rho.
The average SI values in girls and boys were 1.30±0.34 and 1.32±0.22, respectively. There was no significant difference between SI values measured in the head, trunk, and tail of the pancreas (p=0.594). The average SI value did not differ between girls and boys (p=0.751). Correlation analysis revealed that SI was positively associated with age (p=0.005), body weight (p=0.004), height (p=0.003), and BMI (p=0.005).
This study determined normal elasticity values of the pancreas in healthy children. SI values of pancreas change with age, body weight, height, and BMI in the pediatric population. Information obtained from healthy children can serve as a baseline against which pancreatic diseases can be examined.
确定胰腺不同部位的应变指数（SI）值，并研究健康儿童的年龄、性别、体重、身高、体重指数（BMI）与胰腺弹性值之间的关系。
材料/方法：本横断面试验对147名接受经腹超声胰腺弹性成像检查的健康儿童进行。使用凸阵3.5 - 5兆赫探头获取图像。记录包括年龄（月）、体重（千克）、身高（厘米）和BMI（千克/平方米）在内的基线描述性数据。计算胰腺头部、体部和尾部的应变指数值，并得出平均值。评估人口统计学变量与SI值之间的关系。使用Pearson相关系数和Spearman秩相关系数评估正态分布变量之间的相关性。
女孩和男孩的平均SI值分别为1.30±0.34和1.32±0.22。胰腺头部、体部和尾部测量的SI值之间无显著差异（p = 0.594）。女孩和男孩的平均SI值无差异（p = 0.751）。相关分析显示，SI与年龄（p = 0.005）、体重（p = 0.004）、身高（p = 0.003）和BMI（p = 0.005）呈正相关。
本研究确定了健康儿童胰腺的正常弹性值。儿科人群中胰腺的SI值随年龄、体重、身高和BMI而变化。从健康儿童获得的信息可作为检查胰腺疾病的基线。
