Abstract:
Objective To measure the diameter of the corpus callosum in children aged 0-14 years using midsagittal high-resolution MRI,and to find the normal reference values of the diameter of the corpus callosum in children of different ages.Methods The imaging data of 967 children with normal brain MRI were retrospectively selected and grouped according to age.The anteroposterior diameter(APD),thickness of the genu(GT),thickness of the body(BT),thickness of the isthmus(IT),thickness of the splenium(ST)and fronto-occipital diameter(FOD)of the corpus callosum were measured on the midsagittal plane of the brain.The diameters of the corpus callosum on the midsagittal plane of the brain of children at different ages were measured.The correlation analysis between the diameter of the corpus callosum and age were performed.Results The APD,GT,BT,IT,ST and FOD were positively correlated with age(r=0.660,0.590,0.528,0.521,0.660,0.597,P<0.01).The IT variation was the greatest in the subregions of the corpus callosum.The growth peak of GT and ST of corpus callosum appeared before 2 years of age.Conclusion The establishment of the normal reference value of different subregions of the corpus callosum in children can help to accurately evaluate the development of the corpus callosum,which is conducive to the evaluation of the prognosis of diseases related to the corpus callosum.
