正常成年人MDCT门静脉测量的区域性研究

Regional Studies of MDCT Measurement of the Portal Vein in the Normal Adult

目的利用多排螺旋CT(MDCT)测量甘肃地区健康成人门静脉及腹主动脉直径,建立正常成年人门静脉及腹主动脉直径的数值标准。方法回顾性分析2014年2月至2015年4月在兰州大学第一医院行上腹部CT增强检查的正常成年人300例,按年龄分组:18-39岁(A组),40-59岁(B组),≥60岁(C组);各组均包括男50例,女50例。扫描图像经工作站3D重建后进行测量,所得结果利用SPSS22.0统计分析。结果 LPV在A组与C组间有明显差异(P<0.05),MPV在A组与C组、B组与C组间有明显差异(P<0.05),AA、R3在任一年龄组间均有明显差异(P<0.01),LPV、RPV、MPV、AA在性别间有明显差异(P<0.05)。结论门静脉及腹主动脉管径在年龄及性别间差异有统计学意义,本实验为甘肃地区成年人肝脏及门静脉相关疾病的早期诊断提供了客观的影像学量化标准。

Objective To measure the diameters of the portal vein and abdominal aorta of the normal adult in Gansu Province by Multi-detector Row Spiral CT, and determine the normal CT scale of portal vein and abdominal aorta of adult. Methods Retrospective analysis 300 normal cases that were performed enhanced abdomen CT in the First Hospital of Lanzhou University from February 2014 to April 2015. They were equally assigned to 3 groups according to their age（A group：18—39years,B group：40-59 years,C group：be equal or greater than 60 years;50 females and 50 males in each group）. Measurements were done on 3D reconstruction image with precise landmarks, and these data were statistically analyzed by SPSS22.0. Results There were significant differences in the diameters of the left portal vein between group A and group C（P〈0.05）, and the diameters of the main portal vein were significantly diffrent between group A and group C, group B and group C（P〈0.05）, and the diameters of abdominal aorta and R3 differed significantly among each group（P〈0.01）. The diameters of left portal vein,right portal vein,main portal vein, and abdominal aorta differed significantly among the genders（P〈0.05）. Conclusion The diameters of main portal vein and abdominal aorta differed significantly among the age and genders. Imaging standard is provided for Gansu Province adult in early diagnosis of liver or portal vein disease.
