Sequential two-dimensional phase-contrast MR angiography can be used to accurately evaluate the anatomy, patency, and flow direction of the portal venous system and the presence, extent, and distribution of portosystemic collaterals. Its large field of view, insensitivity to the patient's body habitus, and graphic display format make this MR technique extremely useful for preoperative evaluation of patients with chronic liver disease and portal hypertension. This pictorial essay illustrates the spectrum of abnormalities seen on phase-contrast MR angiography of the portal venous system in patients with endstage liver diseases and portal hypertension.
序贯二维相位对比磁共振血管造影可用于准确评估门静脉系统的解剖结构、通畅情况和血流方向，以及门体分流的存在、范围和分布。其大视野、对患者体型不敏感以及图形显示格式使这种磁共振技术对慢性肝病和门静脉高压患者的术前评估极为有用。这篇图文并茂的文章展示了终末期肝病和门静脉高压患者门静脉系统相位对比磁共振血管造影所见异常的范围。
