摘　　要：目的　探讨磁共振血管成像 (MRA)在门静脉高压症血流动力学研究中的应用价值。方法　对 38例肝硬变门静脉高压症病人和 12例非肝硬变对照组病人进行MRA检查 ,检测门静脉系统解剖形态成像和血流量变化 ,分别与间接门静脉造影 (IPVG)和多普勒超声 (DUS)的结果进行比较。结果　MRA成像结果优于IPVG ,能很好显示门静脉系统各属支 ,对流速、流量的测定与DUS有良好相关性。结论　MRA能较好显示门静脉系统解剖影像 ,并可测得其流速、流量 ,应成为门静脉高压症患者血流动力学研究的首选方法。Objective To evaluate the role of magnetic resonance angiography (MRA) in the study of hemodynamics in patients with portal hypertension (PHT). Methods 38 patients with PHT and 12 patients in the control group were selected in this clinical study. 3D DCE MRA and 2D PC MR were used for study of portal venous anatomy and its hemodynamics, and were compared with indirect portal venography (IPVG) and doppler ultrasonography (DUS). Results The anatomical imaging of portal venous system could be clearly displayed in 3D DCE MRA and the imaging quality was better than that of IPVG. The data of hemodynamics from 2D PC MR were closely related to that from DUS. Conclusions MRA, as a non invasive technique, can display the anatomy of portal venous system and investigate its hemodynamics. It is very useful and should be applied for the first choice in the management of patients with PHT.
