Gradient echo (GE)- and spin ehco (SE)- echo planar imaging (EPI) have been used for dynamic susceptibility analysis with each advantage and limitation. SE-EPI with parallel imaging technique at high magnetic field has been presented to compensate low signal-to-noise and long TR for a whole brain coverage. Using the Bookend method with water exchange correction, consequencially acquired relative cerebral blood flow (CBF) images from GE- and SE-EPI have been quantified. quantitative CBF measurement from GE-and SE-EPI has been compared and validated with the published values
