Does high-intensity signal on time-of-flight magnetic resonance angiography indicate carotid plaques at high risk for cerebral embolism during stenting?
HIS in the plaque on TOF-MRA performed for screening could discriminate plaques at high risk for cerebral embolism during CAS.
Arterial vasoconstriction triggered by venous congestion, which is the veno-arterial reflexis seems to be modulated by adenosine, at least partially. This "sensory" reflex requires further pharmacologic physiologic investigation.
