在肝脏的2-D飞行时间MR血管造影（2-D TOF MRA）中，呼吸运动引起的伪影是不可避免的。因此，在7名健康志愿者中尝试使用3-D梯度回波序列进行肝脏的3-D黑血MRA，该序列允许在屏气期间成像。同时行二维TOF MRA检查。在所有受试者中，3-D MRA允许可视化的主干，第一和第二阶分支的门静脉没有中断。7例受试者中有6例（85%）的右侧三级分支可见，无中断。然而，2-D MRA无法显示门静脉左主干的横向部分，门静脉周围也不如3-D MRA清晰。
In 2-D time-of-flight MR angiography (2-D TOF MRA) of the liver, artifacts caused by respiratory motion are unavoidable. Therefore, a 3-D black blood MRA of the liver was attempted in 7 healthy volunteers, using a 3-D gradient echo sequence which allows imaging during breath holding. 2-D TOF MRA was performed as well. In all subjects, 3-D MRA allowed visualization of the trunk, 1st-, and 2nd-order branches of the portal vein without interruption. Right 3rd-order branches were visualized without interruption in 6 of 7 subjects (85%). However, with 2-D MRA, the transverse portion of the left main portal vein could not be visualized in any subject, and the periphery of the portal vein was less clear than with 3-D MRA.
