We propose to use ferumoxytol, an intravascular contrast
agent, to achieve flow-independent black blood imaging
by taking advantage of its strong R2 relaxivity. As our
technique eliminates the need for DIR preparation, we
could achieve higher scan efficiency by interleaving the
imaging slices. Meanwhile the sharpness of the septal
wall is still maintained. It also provides higher SNR
and CNR due to signal boost from ferumoxytol.
