目的:通过DTI评价顺产儿与剖宫产儿大脑髓鞘发育的特点,探讨剖宫产儿与顺产儿不同区域大脑白质的发育差异.方法:选择2~12岁患儿40例,其中剖宫产20例,顺产20例,测量2组不同区域脑白质各向异性分数(fractional anisotropy , FA)值,并比较组内不同区域脑白质及组间脑白质平均FA值.结果:2组胼胝体膝部、压部、内囊前后肢的脑白质FA值组内比较差异均无统计学意义(均P>0.05);2组组间脑白质平均FA值比较,差异有统计学意义(P<0.05).结论:DTI能进一步反映出顺产儿与剖宫产儿脑白质区的发育差异.

Objective:To investigate myelin developmental differences between cesarean and normal delivery by application of diffusion tensor imaging (DTI);evaluating the value of DTI. Methods:Collect 40 cases of 3 to 12 year aged volunteers,the FA values were measured in different regions of the brain white matter between cesarean and normal delivery and then were com-pared. Results:the FA value of Corpus callosum knee,press department,anterior and posterior limbs of internal capsule and the thalamus brain white matter in cesarean delivery or in normal delivery were both no statistically difference (P>0.05),but these FA value between cesarean delivery and normal delivery were statistically difference (P<0.05). Conclusion:Myelin developmen-tal had statistically difference between cesarean delivery and normal delivery. DTI can precisely reactions the development dif-ference of brain white matter in various parts.
