| 目的 基于上腹部增强CT图像获取不同年龄段儿童门静脉直径参考范围。方法 回顾性分析390例门静脉无明显异常患儿上腹部增强CT数据,根据年龄将其分为＜12个月组(A组,n=70)、13~60个月组(B组,n=87)、61~120个月组(C组,n=102)及＞120个月组(D组,n=131)。基于门静脉期重建图像测量门静脉直径并进行组间比较;以Pearson相关分析观察门静脉直径与患儿年龄、身高及体质量的相关性。结果 A~D组门静脉直径分别为(4.79±0.86)、(7.14±1.17)、(9.37±1.41)及(10.79±1.63)mm,随年龄增大而依次递增(P均＜0.001)。各年龄段儿童门静脉直径与年龄、身高及体质量均呈中-高度正相关(r=0.763~0.852,P均＜0.05)而与性别无明显相关(r=0.070,P＞0.05)。结论 初步获得我国不同年龄段儿童门静脉直径参考范围。 |

| Objective To obtain portal vein diameter in children of different ages using upper abdomen enhanced CT. Methods Data of upper abdomen enhanced CT in 390 children without obvious abnormality of portal vein were retrospectively analyzed. The children were divided into ＜12 months group (group A, n=70), 13—60 months group (group B, n=87), 61—120 months group (group C, n=102) and ＞120 months group (group D, n=131) according to age. Portal vein diameter was measured based on reconstructed images of portal vein stage and compared among groups. Pearson correlation analysis was performed to observe the correlations of portal vein diameter with age, height and body mass, respectively. Results Portal vein diameter in groups A to D was (4.79±0.86), (7.14±1.17), (9.37±1.41) and (10.79±1.63) mm, respectively, which enlarged successively with the increase of age (all P＜0.001). Portal vein diameter in children of different ages were moderately to highly positively correlated with age, height and body mass (r=0.763—0.852, all P＜0.05), but not significant correlated with gender (r=0.070, P＞0.05). Conclusion The reference range of portal vein diameter in children with different ages in China were preliminarily evaluated. |
