| 目的 评价三维动态对比增强MRA(3D-DCE MRA)在门静脉系统成像中的应用价值。方法 对肝硬变门静脉高压症患者52例和非肝硬变对照组患者20例进行研究。采用Philips Gyroscan T10-NT(1.0T)超导MR机,应用3D-DCE MRA技术进行门静脉系统成像。结果 95.8%门静脉主干显示清楚或较清楚,血管边界光滑,脾静脉及肠系膜上静脉显示较好则分别达到91.2%和90.3%。肝硬变门静脉高压症患者中,48例显示不同程度的食管胃底静脉曲张。在非肝硬变对照组患者中,肝门静脉灌注明显好于肝硬变患者。结论 3D-DCE MRA作为一种新的无创性血管造影技术,可很好显示门静脉系统,具有重要的应用价值。 |

| Objective To evaluate 3D-DCE MRA in the imaging of portal venous system. Methods There were 52 patients with portal hypertension and 20 without liver cirrhosis. On a Philips Gyroscan T10-NT(1.0 Tesla) MR imaging system, 3D-DCE MRA was used to show the anatomy of portal venous system. Results The visualization rate for portal vein, splenic vein and superior mesenteric vein reached as high as 95.8%, 91.2% and 90.3%, respectively. Esophageal-gastric varices were detected in 48 patients with portal hypertension. As perfusion of portal vein to liver was concerned, it was significantly better in the control group than in those who suffered from liver cirrhosis. Conclusion It indicates that the anatomical imaging of the portal venous system can be clearly revealed in 3D-DCE MRA. |
