健康成人骨盆骨髓扩散加权成像性别、年龄间差异及相关性研究
Journal of Clinical Radiology(2016)
Abstract
目的 探讨健康成人骨盆骨髓扩散加权成像(DWI)性别、年龄间差异及相关性.方法 回顾性分析230名健康成人骨盆DWI检查资料.将骨盆骨髓扩散信号分为3大型并测量ADC值,分析骨盆骨髓扩散分型及ADC值年龄、性别间差异及相关性.结果 男性30岁前后、女性50岁前后骨盆扩散分型变化明显,20 ~ 50岁间男女骨盆扩散分型差异明显,50岁以后差异不显著.20~50岁间,女性髂骨、坐骨ADC值高于男性,50岁以后女性耻骨ADC值高于男性,且骨盆扩散信号、ADC值与年龄存在一定负相关.结论 骨盆DWI可用来反映骨髓年龄、性别间差异.
