Attaining reproducible, time-efficient, high spatial resolution and quantitative MRI perfusion images in small animal MRI @9.4T is still challenging. To take a step toward this goal, perfusion data from arterial spin labeling (ASL), Flow-sensitive Alternating Inversion Recovery (FAIR), dynamic susceptibility contrast (DSC), and pseudo-continuous arterial spin labeling (pCASL) sequences are compared by assessing cerebral perfusion in 5 rats, each scanned 3 times. Differences in (cerebral blood flow) CBF in major brain regions were analyzed, and the repeatability of perfusion MRI was assessed.
