We have tested the feasibility of high-resolution
(1.15mm x 1.15mm x 3mm) arterial spin labeling (ASL)
fMRI for detecting changes in CBF due to motor
activation at 3T. The SNR of the high-resolution ASL was
compared to that of the commonly used low-resolution ASL,
with and without correcting for partial volume effects.
Availability of high-resolution CBF imaging should
increase the utility of ASL for clinical and
