摘要 目的探讨MR扩散张量成像技术在常规MR平扫正常的儿童发育迟缓诊断中的价值。方法前瞻性搜集常规MRI正常的25例发育迟缓儿童(其中男14例,女11例)及25例同龄、性别匹配的对照组发育正常儿童进行常规MRI及DTI检查。并分别选取两侧大脑半球4个浅部脑白质及5个深部脑白质,测量其FA值及MD值,并配对t检验分析其差异。结果发育迟缓组儿童浅部脑白质及视放射区FA值明显低于对照组(P<0.05),发育迟缓组浅部脑白质MD值明显高于正常对照组(P<0.05);发育迟缓组深部脑白质MD值与同龄对照组无统计学差异(P>0.05)。结论扩散张量成像技术可用于对常规MR平扫正常的发育迟缓患儿脑白质损伤的定量诊断,为儿童发育迟缓的临床治疗提供依据。
