Abstract:
Objective To discuss the feasibility of computerized tomography (CT) calibration technique for the quantification of the hepatic fat content in vivo . Methods Eleven healthy volunteers, 53 patients with fatty liver, 10 cases of chronic hepatitis B and 10 cases of liver cirrhosis were tested with CT calibration test tubes. Test tubes contained solutions with Terbutyl alcohol, which CT scan density (CTD) is close to fat tissue, and 18.5% glucose solution which CTD is almost identical to normal liver. Variable Terbutyl concentrations of 10%, 20%, 30% and 40%, which stands for various fat content in liver, were used to measure patients with variable degrees of steatosis under CT scan. Results There was a negative linear correlation ( r = -0.982 , P
