1 Globally increased ASL signal intensity due to artifact.
Globally increased ASL signal intensity due to artifact. Perfusion pattern appears normal except for high signal intensity in the lateral ventricles (arrows), due to shinethrough of T2-weighted signal intensity that was not adequately suppressed during only 1 volume (vol 10). Vol 11 represents a normal control-label image subtraction obtained during signal intensity averaging. A.R. Deibler et al. AJNR Am J Neuroradiol 2008;29: ©2008 by American Society of Neuroradiology
