Schematic diagram of the principles of FE-MRI.

Caption

During the blood pool phase, it significantly shortens the T1 and T2 relaxation times of the blood, thus achieving bright blood effects in T1-weighted imaging and dark blood effects in T2/T2*-weighted imaging. In the delay phase, by the local aggregation of ferumoxytol disrupting the uniformity of the local magnetic field, the decrease of the transverse magnetization vector Mxy is expedited, resulting in a negative contrast effect.
