The aim of this study was to develop a practical and robust perfusion measurement with high sensitivity and stability in the mouse brain at high magnetic field strength, via the combination of flow-sensitive alternating inversion recovery (FAIR) and single-shot k space-banded gradient- and spin-echo (kbGRASE). To estimate the influence of physiological parameters on the precision and reproducibility of CBF measurements, changes in anesthesia regime, hypercapnia and body temperature were performed.
