摘要 近年来,随着磁共振新技术的发展,三维动态增强磁共振血管成像(Three—dimensional dynamic contrast—enhanced magnetic resonance angiography,3D DCE MRA)技术逐渐成为体部血管成像的主要方法,它可以多角度、多方位显示肝内血管的解剖关系,同时,采用血流动力学自动分析软件测量肝内血管的血流速度、直径、血流量等指标,为临床提供一个更全面更为客观的诊断信息。目前,3D DCE MRA技术在腹部大血管病变中的应用研究较多,而对肝血流流速测定的研究较少,本文就3D DCE MRA测定肝血流流速的基本原理、临床应用及进展做一综述,以期提高对该技术的认识。
