CT观察与测量国人儿童正常胰腺

CT measurements and meanings of normal pancreas in Chinese children

目的通过观察国人儿童正常胰腺CT图像,得到不同年龄段国人儿童胰腺不同部位径线CT测量值的参考范围,为判断儿童胰腺形态、大小异常提供依据。方法选取接受腹部CT增强扫描的无胰腺疾病及其他相关疾病儿童200例,按年龄分为婴儿期(<1岁)、幼儿期(1～2岁)、学龄前期(3～6岁)、学龄期(7～12岁)和青春期(13～16岁),测量每组胰头左右径、胰颈前后径和胰体前后径的最大径线长度,并进行统计学处理。结果胰头左右径、胰颈前后径和胰体前后径最大径线长度在婴儿期分别为(11.50±3.24)mm、(6.60±2.11)mm、(9.52±3.37)mm,幼儿期分别为(15.28±3.38)mm、(9.16±3.01)mm、(14.67±1.61)mm,学龄前期分别为(17.66±4.99)mm、(11.05±3.48)mm、(17.26±1.98)mm,学龄期分别为(18.87±4.06)mm、(12.04±4.25)mm、(19.83±3.91)mm,青春期分别为(21.71±7.60)mm、(15.76±1.82)mm、(22.93±4.37)mm;不同年龄期胰腺各部位的径线随着年龄的增加而增加差异有统计学意义(P<0.05);同年龄期不同胰腺部位间径线长度的差异有统计学意义(P<0.05)。结论本研究初步得到不同年龄段国人儿童胰腺径线的相关正常值,可作为检测儿童胰腺疾病发生、转归提供重要依据。

Objective To provide references for diagnosis of abnormal pancreas morphology, and to establish the range of the normal pancreas thickness using CT measurement in different age groups. Methods A total of 200 children without pancreatic diseases were examined with CT, and were divided into 5 groups according to age, i.e. infant group （〈1 year- old）, child group （1-2 year-old）, preschool group （3-6 year-old）, school-age group （7-12 year-old） and adolescent group （13-16 year-old）. The diameters of pancreatic head, the neck of pancreas and pancreatic body were observed and measured on CT images, and then analyzed statistically. Reaults The diameter of pancreatic head, the neck of pancreas and pancreatic body in 5 groups was （11.50±3.24）ram, （6.60±2.11）ram and （9. 52±3.37）ram in infant group, （15.28 ±3.38）ram, （9.16± 3.01 ）mm and （14.67± 1.61 ） mm in child group, （17.66 ± 4.99） ram, （ 11.05 ± 3.48） mm and （17. 26±1. 98） mm in preschool group, （18.87±4.06）mm, （12. 04± 4. 25） mm and （19. 83±3.91）mm in school-age group, while （21.71±7.60）mm, （15.76±1.82）ram and （22.93±4. 37）ram in adolescent group. The diameters increased with age （P〈0.05）, and there were significant differences among the different site in pancreas （P〈0.05）. Conclusion The data of this study based on image anatomy with regard to the pediatric pancreas are useful for the diagnosis and treat- ment of pancreatic disease in Chinese children.
