Analysis on the ultrasonography in measurement liver sectional area to estimate the liver volume with 214 cases

Objective:To explore a new method with ultrasonography to measure liver section area,and assess the significance of liver size. Methods:Two hundred and fourteen cases were selected with ultrasonography examination without liver disease and liver enlargement factor,the right liver lobe anterior oblique section area and left hepatic lobe area of longitudinal section were measured. The measured result were compared in different genders,and age groups. The sum of two section area of liver and CT measurement of liver volume were compared and analyzed. Results:The right liver lobe anterior oblique section areas in 97 cases of normal male were(95.31±22.95) cm2,The longitudinal area of the left lobe was(28.37±7.77) cm2; The right liver lobe anterior oblique section area in 117 normal female was(84.99±16.91) cm2,left lobe longitudinal area was(25.37±5.56) cm2; the two section area of males was larger than that of females(P0.01),There was no statistical difference in young,middle-aged,and the elderly group; normal human liver around the two area and CT measured liver volume was significantly positive correlation(r=0.511,P=0.000),liver volume and liver two cutting surface area and the regression equation was LV=940.8+2.1S(cm2). The ratio of longitudinal section area of the left lateral lobe area,and right hepatic lobe anterior oblique section area was 3.47±0.87,presenting normal distribution. Conclusion:Ultrasonography measurements of normal human liver right lobe anterior oblique section area and left lateral lobe longitudinal area can be used to evaluate the liver size. The method is simple and practical.
