다국어 초록 (Multilingual Abstract)

Although many approaches have been attempted in the evaluaion of liver size such as measurement of length, area and volume, the linear measurements have been used most frequently because of simplicity. We measured the liver size using 4 linear measurements for evaluation of hepatic pliability on plain abdominal film in the erect and the supine position. Our cases consisted of 125 persons who have no symptom or signs clinically and have normal liver funcion test. The results were as follows : 1. The measurements of the liver size using diagonal diagmeter(DD), oblique diameter of right lobe (DD), midline vertical diamenter(MD) and height of right dome of the liver(HD) were ; 19.6$\pm$1.8 cm, 21.0$\pm$ 1.8cm , 13.7$\pm$ 1.6cm, 2.03$\pm$0.4cm in the supine position ; and 20.5$\pm$2.1cm , 21.9$\pm$ 2.1cm, 15.4$\pm$2.2cm 1.87$\pm$0.4cm in the erect position respectively. 2. The differences of each diameter between erect and supine position were 0.9$\pm$1.0cm in DD, 0.9$\pm$1.0cm in OD and 1.7$\pm$1.3cm in MD, and t ey were longer in the erect position than in the supine position(P<0.001). 3. The HD was slightly longer in the supine position than in the erect position(P<0.001). 4. Among the 4 measurements, the largest difference of linear diameter between the erect and the supine position was by MD. 5. We found the change of size and shape of the normal liver in different position.
