摘要 目的探讨儿童胼胝体压部纤维束发育规律。方法 120名健康儿童(年龄5d～14岁)分为5组,≤1岁为第1组(22名),>1岁～3岁为第2组(20名),>3岁～6岁为第3组(22名),>6岁～10岁为第4组(30名),>10岁～14岁为第5组(26名)。分别行脑部常规MRI和弥散张量成像(DTI)扫描,对原始数据进行弥散张量纤维束成像(DTT)重建,并对所得数据进行统计学分析。结果婴幼儿、学龄期儿童和青春发育期儿童胼胝体压部纤维束的密度分别为432(256～512)、580(355～710)和754(580～900)。结论儿童白质纤维束随年龄增长而增多。 Objective To study the development of splenium corporis eallosi in children. Methods One hundred and twenty healthy children （5 days-14 years） were classified into five groups： group 1 （ ≤ 1 year old） , group 2 （ 〉 1-3 years old）, group 3 （〉3-6 years old）, group 4 （ 〉6-10 years old） and group 5 （ 〉 10-14 years old）, and underwent conventional magnetic resonance imaging （MRI） and diffusion tensor imaging （DTI）. Fibers were reconstructed through raw data by diffusion tensor tractography （DTT） and were analyzed statistically. Results The density of fibers of splenium corporis eallosi in young children, school age children and adolescence period children were 432 （256-512） , 580 （355- 710） and 754 （580-900） respectively. Conclusion White matter fibers are increased with the age of the children.
