Determination of CT Number of Normal Liver in Sudanese Population using Computed Tomography

Abstract

To determine the liver CT number among Sudanese people using spiral CT. A designed data sheet was used to collect data from 50 patients refer to CT abdomen , which was done using images of slice thickness (5mm) and slice gap (7-10mm) , three readings were taken from three points in axial cuts. The mean CT number of liver among the males was found to be 57.24±7.98 HU , and that among females was 56.19±10.77 the mean different was found to be 1.05 which was statically insignificant within p-value of 0.932 . When the patients age was correlated to the CT number of liver , the relationship was found to be a weak positive relationship with correlation coefficient of r=0.027 , this relationship was found to be statically significant within p-value of 0.932 . The mean of CT number of normal liver among Sudanese patients was found to be 56.90±8.87 HU , the CT number of normal liver is not affected by gender , age affects liver CT number with a weak direct relationship .
