磁共振成像和血清铁蛋白评估铁过载的对比研究(3)

     我们的研究中有10例患者在检查前3个月内未接受过祛铁治疗,评估这些患者肝脏T2*与ASF的关系时发现,这些患者肝脏T2*与ASF的相关性更高(r=-0.866,P=0.001)。同样在肝脏T2*及ASF与输血量的关系评估中发现,这些患者肝脏T2*与输血量之间的线性关系未见明显变化,但ASF与输血量之间的关系出现了明显的变化,由无相关性变为存在线性相关(r2=0.63,P=0.006),由此可见,短期的祛铁治疗对ASF的改变更大一些,祛铁治疗时SF的改变是早于肝脏T2*的。但我们所选取的病例无长期、规律祛铁治疗的患者,祛铁治疗对于肝脏T2*的影响情况还需后续研究。

    肝脏T2*与血清铁蛋白之间存在显著负相关性,但较之血清铁蛋白,肝脏T2*更能准确的描述患者铁过载情况,可信度及重复性更佳,选用肝脏T2*才能更确切的判断患者铁过载情况及更准确的选择祛铁治疗时机。
