Observational Study Of Measurement Of The Portal Vein In Gansu Normal Adults With MDCT

Objective To measure the diameters of the main portal vein,left portal vein,right portal vein and abdominal aorta of the normal adult in Gansu Province by Multi-detector Row Spiral CT,determine the normal CT scale of portal vein and abdominal aorta of normol adult.And the diameter features of the portal vein were measured of the normal adult in Gansu comparative analysis the other’s data reported in the previous bibliography at home and abroad.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—59years,C group:be equal or greater than 60 years;100 patients in each group,including 50 females and 50 males).Measurements were done on 3D reconstruction image with precise landmarks,send to picture archiving and communication system(PACS) for measuring, measuring three times average respectively,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. Multi-detector Row Spiral CT–three dimensional reconstruction can be shows portal system and abdominal aorta clearly. Imaging standard is provided for Gansu Province adult in early diagnosis of liver or portal vein disease.
