摘要
目的探讨CT测量正常人肝脏体积及相关评估肝脏大小的方法及其意义。方法选择无肝脏疾病和引起肝脏增大因素的CT检查者241例,测量计算正常成人肝脏的体积、最大平面面积和肝门平面面积。对不同性别、年龄组的测量结果进行比较分析。结果122例男性和119例女性的肝脏体积分别为(1074.89±234.98)cm3和(954.53±195.22)cm3(P<0.001);最大平面面积分别为(153.25±24.97)cm2和(136.28±18.39)cm2(P<0.001);肝门平面面积分别为(142.96±25.28)cm2和(128.63±16.83)cm2(P<0.001),男性肝脏总体上显著大于女性。随着年龄的增大,肝脏的体积、最大平面面积和肝门平面面积均有缩小趋势。肝脏的体积与最大平面面积、肝门平面面积密切相关,尤其是肝脏体积与最大平面面积之间的相关系数在0.78以上。结论正常人肝脏的体积与最大平面面积、肝门平面面积具有显著相关性,尤其是肝脏最大平面面积可用于临床评估肝脏的大小,方法更为简便。肝脏大小与年龄、性别有一定的关系。
Objective To discuss tbe method of CT measurement of the liver volume and method of evaluating hepatic size in normal adult and their significance. Methods 241 cases without liver diseases and hepatomegaly were selected. Their liver volume, the maximal and hepatic hilar cross-sectional areas in normal adult were obtained from abdominal CT examinations. The hepatic sizes in relation to age and gender were compared. Results The mean value of the hepatic volume was （1 074.89±234.98） cm^3 in 122 men and（954.53±195.22）cm^3 in 119 women （P〈0.001）, the maximal cross sectional area was（ 153.25 ±24.97）cm^3 and（ 136.28 ± 18.39）cm^2 （P〈0. 001 ）, the hepatic hilar cross-sectional area was（142. 96 ± 25. 28 ） cm^2 and（128.63± 16.83）cm^2（P〈0.001）. In total, the liver in men was bigger than that in women. Along with age increasing, the liver volume, the maximal and hepatic hitar cross sectional areas in normal adult have a tendency of shrinking. The liver volume correlated well with the maximal cross-sectional areas and the hepatic hilar cross-sectional areas, especially, correlation coefficient between liver volume and maximal cross sectional areas were a bove 0.78. Conclusion The liver volume in normal adult correlated closely with the maximal and the hepatic hilar crosssectional areas, especially, the maximal cross-sectional areas may be used for evaluating the size of liver is clinically. The method is simple and convenient. The size of liver is related to age and gender in a certain extent.
