[Contribution of arterial spin labeling to the diagnosis of sudden and transient neurological deficit].

Abstract : MRI is the gold standard exploration for sudden transient neurological events. If diffusion MRI is negative, there may be a diagnostic doubt between transient ischemic attack and other causes of transient neurological deficit. We illustrate how sequence arterial spin labeling (ASL), which evaluates cerebral perfusion, contributes to the exploration of transient neurological events. An ASL sequence was performed in seven patients with a normal diffusion MRI explored for a transient deficit. Cortical hyperperfusion not systematized to an arterial territory was found in three and hypoperfusion systematized to an arterial territory in four. ASL helped guide early management of these patients.
