The
purpose of this study was to evaluate the ability of 2D ToF-MRA to depict
cerebral arteries in the canine brain and to compare the results obtained
from a high field magnet (3T) with an ultrahigh field magnet (7T). ToF-MRA at
high and ultra-high magnetic fields should be included in the MRI imaging
protocol of dogs suspected of having cerebrovascular disease. 7T field
ToF-MRA allows a better delineation of small vessels in the canine brain than
3T ToF-MRA.
