title: [A comparison of the quantified determination of the echogeneity of the liver by ultrasound and the density of the liver by CT].
abstract: A defined region of the right lobe of the liver was measured by grey scale analysis based on similar presets according to a manual input of a Region of Interest (ROI). During 20 days, the livers of healthy subjects were tested by this method in order to test the reproducibility of the results. By prospective studies, the livers of 30 patients were examined by ultrasound and CT regarding the determination of the extent of their fatty liver disease. The value of the density of liver was determined in Hounsfield units (HU). Both methods lead to parameters that characterise the fatty content of the liver. Statistic analysis shows acceptable correlation of both methods. By means of grey scale analysis in ultrasound measurements it is possible to estimate the extent of the fatty content of liver.
