Pseudo Continuous Arterial Spin Labeling MR Imaging of Status Epilepticus

Purpose: The purpose of this study was to describe arterial spin labeling MR image findings of status epilepticus. Materials and Methods: A retrospective chart review within our institute revealed six patients who had been clinically diagnosed as status epilepticus and had also undergone MR imaging that included ASL in addition to routine sequences. Results: Six patients with status epilepticus were studied by conventional MR and arterial spin labeling imaging. All patients showed increased regional CBF correlating with EEG pathology. Notably, in two patients, conventional MRI and DWI showed no abnormal findings whereas pCASL demonstrated regional increased CBF in both patients. Conclusion: Arterial spin labeling might offer additional diagnostic capabilities in the evaluation of patients with status epilepticus. Index words: Status epilepticus∙Arterial spin labeling∙Cerebral blood flow∙Magnetic resonance imaging (MRI) Status epilepticus (SE) is a life-threatening neurologic emergency condition that requires prompt treatment. If it is not successfully treated, SE may lead to permanent pathological damage and altered physio-logical function of the brain resulting in significant morbidity or mortality (1-5).
