摘要
目的:探讨CT测量正常成人脾脏大小的方法及其相关因素。方法:选择无引起脾脏增大因素的CT检查者241例。测量计算正常成人脾脏的体积、最大平面面积和脾门平面面积。对不同性别、年龄组的测量结果进行了比较分析。结果:122例男性和119例女性的脾脏体积分别为139.13±53.64 cm3和122.52±50.46 cm3(P=0.014);最大平面面积分别为27.74±8.22 cm2和25.08±6.75 cm2(P=0.007);脾门平面面积分别为25.67±8.12 cm2和23.34±6.55 cm2(P=0.015)。随着年龄的增大,脾脏的体积、最大平面面积和脾门平面面积均有缩小趋势,但各年龄组之间无显著性差异。脾脏的体积与最大平面面积、脾门平面面积之间的相关系数分别在0.839和0.758以上。结论:正常成人脾脏的体积与最大平面面积、脾门平面面积具有密切的相关性,后两者可用于临床评估脾脏的大小。脾脏大小与年龄、性别有一定的关系。
Objective： To explore the method of CT measurmeent of the spleen in adult and relative factors. Methods： Two hundred and forty-one cases without any splenic diseases were selected. The splenic volume,maximal and splenic hilar level areas were obtained from CT images. The splenic sizes in relation to age and gender were compared. Results： The mean value of the splenic volume was 139.13±53.64 cms in 122 men and 122.52±50. 46 cms in 119 women （ P =0. 014）,the maximal cross-sectional area was 27.74± 8.22 cm^2 and 25.08±6.75 cm^2（ P =0. 007）,the splenic hilar cross-sectional area was 25.67±8. 12 cm^2 and 23.34±6.55 cm^2（ P =0. 015）. Along with age increasing,the splenic volume,the maximal and splenic hilar cross-sectional areas in normal adult were shrinking tendency. There were no significant deviations among each age groups. The splenic volume correlated well with the maximal cross-sectional areas and the splenic hilar cross-sectional areas, their coefficient correlation were above 0. 839 and 0. 785, respectively. Conclusion： The splenic volume in adult is correlated closely with the maximal and the splenic hilar cross-sectional area,the latter may be used for appraisal of the size of spleen clinically. The size of spleen relate to age and gender in a certain extent.
