Imaging the major arteries in the brain is straightforward using MR angiography either with or without a contrast agent. However, imaging vessels at the 250μm level is challenging and imaging vessels at the 50μm to 100μm level is essentially impossible even with high field systems. One potential approach to bring them to life is using an iron-based contrast agent to enhance SWI. In this work, we extend the use of Ferumoxytol to image the small cerebral arteries and veins to 3T and show that within a reasonable scanning time, one can obtain superb images of the vasculature of the brain.
