SONOGRAPHIC MEASUREMENT OF THE NORMAL LIVER MARGINAL ANGLES
Abstract
The liver marginal angles have been measured in 937 normal health check-up subjects by ultrasound. They were 57.7 % men and 42.3 % women. The aims of this study were to evaluate correlation between liver marginal angles and physical data, age, sex. The results show that the mean of weight, height, BMI and LIMA in male were larger than female. The average of LLMA, LIMA and RIMA were 41.6 ± 4.4, 39.3±4.3 and 45.9± 8.6 degrees, respectively. There were negative correlation between age and sex, age and weight, age and height, while correlation between sex and weight, sex and height, sex and AP diameter were positive. Sex can predict the LIMA from the equa- tion: LIMA = 38.17+2.09 (sex)......equation I. Physical data that were used to predict the RIMA were BMI and height from the equation: RIMA = 56.89 +1.05 (BMI) - 20.27 (Ht). From the classification of obesity, mean BMI was 21.42 kg/m2(body surface area) for men, 20.89 kg/m2 for women. Among the normal health check-up subjects, the over- weight group constitutes 7.3 % of the total cases.
