Many methods have been described for the mensuration of the liver volume and weight, and most of theso, including the plain roentgenograms, often gives erroneous results. With the successful outlining of the liver by the scintillation scanning, it was felt that the use of the scanning would be helpful in the measurement of the liver weight. The auther intended to estimate the normal liver weight and the normal Korean adults for establishing the normal standard value. This report includes the study of 256 normal autopsy in regard of the liver and 271 normal liver scanning, and analyzed them with regard to sex, age and body surface area. The author obtained some results as following; 1. The liver weight of the normal Korean adults is 1323 Gm., and varied from 850Gm. to 1938 Gm. 2. The relative liver weight of the normal Korean adults are 855 Gm., and varied from 846Gm. to 875 Gm. 3. There are proportional corelation between the liver weight and body surface area.
