Neuroimaging of the epilepsies
نویسنده
چکیده
The superiority of magnetic resonance imaging (MRI) over X-ray computed tomography (CT) scanning in terms of sensitivity and specificity for identifying the aetiology of epilepsy in both adults and children is firmly established. The most common abnormalities identified are hippocampal sclerosis (HS), malformations of cortical development (MCD), vascular malformations, tumours, and acquired cortical damage. X-ray CT, however, may be preferred to MRI if a patient is disturbed or acutely unwell, as the patient is more accessible during the procedure. An X-ray CT scan is also valuable for the investigation of possible acute intracranial haematomas and skull fractures, and if there is a contraindication to MRI such as a cardiac pacemaker or cochlear implants. CT is also useful as a supplement to MRI for clarification of possible intracranial calcification that is not shown easily by MRI.

Temporal Plus Epilepsies: The Outcome after Non Invasive Presurgical Evaluation
Temporal plus epilepsies are a relatively frequent undiagnosed condition in temporal lobe epilepsies. We report two cases of temporal plus epilepsies suspected on ictal clinical and scalp-video EEG findings. No invasive EEG or functional imaging was performed since clinical, neuropsychological, neuroimaging data and video-EEG recordings are concordant. Our two patients underwent temporal lobect...

We evaluated the clinical characteristics and the electroencephalographic (EEG) findings by long video-EEG monitoring in 64 successive patients with definite nocturnal seizures. Mental state, neurological examination, neuroimaging and EEG background were normal in all patients. Classification of epilepsies was possible in 42 out of 64 (66%) patients according to the revised Classification of Ep...
متن کاملTexture analysis of magnetic resonance images of patients with juvenile myoclonic epilepsy
BACKGROUND/PURPOSE Juvenile myoclonic epilepsy (JME) is the most frequent subsyndrome of the idiopathic generalized epilepsies, and experimental investigations support that the thalamus is a key structure in the mechanisms of JME. Texture analysis (TA) is an image processing technique which can be used to characterize images such as MRI. OBJECTIVE The goal of this work was to investigate the ...
