The purpose of this study is to evaluate the
reproducibility across magnetic field of cerebral blood
flow (CBF) quantification using Arterial Spin Labeling
(ASL) methods. Three ASL methods (pulsed ASL (PASL),
continuous ASL (CASL), and pseudo-continuous ASL
(pCASL)) were evaluated at 4.7, 7, and 11.7T in 43 rats.
Among the three techniques evaluated, pCASL appears as
the most reproducible method across magnetic fields.
