Absolute
cerebral blood volume (aCBV) can be assessed by utilizing the signal
difference of vascular space occupancy (VASO) sequence before and after
injection of T1 shortening contrast agent.
We propose an alternative method to reduce the T2 effect when using
relative long TE. Pre and post T1
fitting were used to reconstruct IR images without the post contrast T2
shortening effect. Experiments on rat
model were conducted to investigate the feasibilities.
