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.
