Inflow magnetic resonance angiography (MRA) plays an important role in catheter insertion for intracranial endovascular treatment in the visualization of blood vessels at the aortic arch bifurcation. However, it is often difficult to accurately determine vascular stenosis due to respiratory artifacts and surrounding fat. In this study, we employ 3-dimensional time of flight MRA using radial-based gradient echo pulse sequence with modified DIXON (TOF-RADIXON) compared it with 3-dimensional time of flight MRA (TOF-MRA). The experimental results using TOF-RADIXON showed that ability to visualize blood vessels is more promising than TOF-MRA.
