摘　　要：目的研究多层螺旋CT测量肝脏体积与中国健康成人性别、年龄、及体表面积之间的相关性,推导出适合中国国人的标准肝体积公式。方法回顾性分析南京医科大学第一附属医院影像科240名影像学检查阴性的受试者的临床资料,数据用x珋±s表示;分别按年龄及性别各分6组,每组男20名、女20名。用统计学方法进行直线相关性与回归分析并进行假设检验。结果 240名受试者测得平均肝脏体积为(1184.43±224.58)cm3,与体表面积及年龄之间存在着相关性,r为0.793,决定系数r2为0.490,均有显著性(P<0.01),并用体表面积、年龄与肝脏体积建立回归方程。结论肝脏体积在性别之间,不同年龄及体表面积之间具有一定规律性;适合中国国人的标准肝脏体积公式LV(cm3)=824.054BSA(m2)-3.489AGE(y)-36.75。Objective To study the correlation between the healthy Chinese adults＇ sex, age, body surface area（BSA） and liver volume measured by using 16 slice spiral CT, and to develop a formula estimating standard liver volume （SLV） for healthy Chinese adults. Methods The clinical data of 240 healthy subjects from July 2010 to July 2011 were reviewed retrospectively. All subjects were divided into six groups by age and gender. In each group, there were 20 men and 20 women. Statistical analysis was used to evaluate the relationship between general characteristics and liver volume measured by 16 slice spiral CT and to develop a formula for calculating the total liver volume. Results Liver volume of 240 subjects was （ 1184.43 ＋ 224.58） em3 , correlations between BSA and age were found （ r = 0. 793,r2 = 0. 490,P 〈 0.01 ）. Re- gression equations were established between liver volume, BSA and age. Conclusion Liver volume has correlation be- tween sex, age and BSA. The standard liver volume of Chinese adults can be calculated as： LV -- 824. 054BSA （ m2 ） - 3. 489AGE （ v ~ - 36.75.
