Determination of Liver Dimensions for Sudanese using Computed Tomography

Abstract

This is an analytical descriptive research, carried out in Khartoum state in the period of December 2012 and February 2013 at Jarash international specialized hospital which aimed to determine the liver span dimensions among Sudanese people, the researcher examined a random sample of 50 Sudanese patients their age ranged from 19 and greater than 63 years old in order to fulfill the research objectives, the researcher extracted despite of the gender difference that the Anteroposterior diameter of left lobe equals 6.09 ± 1.212 cm, Transverse diameter of right lobe equals 8.21 ± 1.03 cm, Transverse diameter of caudate lobe equals 4.32 ± 1.12 cm, Left hepatic boarder angle equals 46.33 ± 10.39 degrees and Caudate Lobe/Right Lobe found to be 0.53 ± 0.14. In this study the researcher test the anteroposterior diameter of left lobe, transverse diameter of right lobe, transverse diameter of caudate lobe and left hepatic boarder angle with patient age and height and found that only the left hepatic boarder and the transverse diameter of right lobe have a significant correlation with the patient age and height as constant predictors through those equations respectively {0.197× age + 37.26} ± 9.8 and (0.027× height + 3.727) ± 2.063. The conclusion is that the Sudanese people have larger liver span dimensions regarding the anteroposterior diameter of left lobe, transverse diameter of right lobe, transverse diameter of caudate lobe and the left hepatic boarder angle in addition to caudate right lobe ratio in contrast with the global reference of liver span dimensions, where globally the normal ratio between the caudate lobe and right lobe is 0.37 ± 0.16 were in the researcher study is found 0.53 ± 0.14 in addition to that the anteroposterior diameter of left lobe is 6.09 ± 1.212 cm were it been reported globally to equal 5 cm when had been measured on the paravertebral line.
