Lipid core is an important indicator for high-risk
atherosclerotic plaque. Diffusion weighted imaging has
great potential for lipid core imaging without
gadolinium injection. The DIR based diffusion weighted
black blood imaging (BB) scheme required long
preparation time and thus has low time efficiency. iMSDE
is a BB sequence which has advantages in regions with
complex and slow flow without long presaturation time.
In this study, we investigate the diffusion weighted
iMSDE (DiMSDE) scheme by introducing appropriate m1 into
the diffusion gradients. Experiments shows this scheme
is effective for both diffusion weighted imaging and
black blood imaging.
