Quantitative susceptibility mapping (QSM) has the
potential to quantify contrast agent bio-distribution.
The purpose of this study is to develop a QSM technique
with sufficient temporal resolution for mapping first
pass contrast agent concentration in cerebral perfusion
imaging.Initial in-vivo brain imaging data demonstrated
the feasibility of mapping time resolved contrast agent
quantification using the proposed method. Cerebral blood
flow agrees with that obtained from arterial spin
labeling technique.
