Nonspecific incidental brain lesions (NILs) are being detected more frequently because of an increasing number of screening or research MRI scans of the brain, and their natural course is uncertain.
METHODS
In a prospective cohort study starting in 1999, we determined the outcomes of patients with
PURPOSE
A recent study reported on high, longer lasting and finally reversible cerebral uptake of O-(2-[
18F]fluoroethyl)-L-tyrosine ([
18F]FET) induced by epileptic activity. Therefore, we examined cerebral [
18F]FET uptake in two chemically induced
Kyotorphin (Kyo) is synthesized in specific brain regions where it may modulate synaptic transmission and directly excites cortical neurons, and indirectly exerts opioid actions to produce analgesia via release of met-enkephalin. Kyo is formed by specific enzyme from L-tyrosine and L-arginine in the
Regular exercise and amino acid supplementation, popular approaches toward the reduction of epileptic seizures, have been extensively researched. This study was conducted to evaluate the effects of treadmill exercise and L-tyrosine treatment on the frequency and amplitude of epileptiform activity in
O-(2-18F-fluoroethyl)-l-tyrosine (18F-FET) PET is a well-established method increasingly used for diagnosis, treatment planning, and monitoring in gliomas. Epileptic activity, frequently occurring in glioma patients, can influence MRI findings. Whether seizures also affect 18F-FET PET imaging is
OBJECTIVE
The objective of this analysis is to review a spectrum of functional brain imaging technologies to identify whether there are any imaging modalities that are more effective than others for various brain pathology conditions. This evidence-based analysis reviews magnetoencephalography
Functional imaging studies complement structural magnetic resonance imaging (MRI) in the assessment of patients with brain tumor-associated focal epilepsy. (11)C-Methionine (MET) and (18) F-fluoro-ethyl-L-tyrosine (FET) are amino acid analogues that highlight metabolically active areas in positron
Primary central nervous system vasculitis is confined to the brain and spinal cord. While serological markers of inflammation are usually normal, conventional angiography may confirm the diagnosis. The diagnostic method of choice is central nervous system biopsy. A 57-year-old man suffered from a
We describe serial studies of focal cortical dysplasia causing temporal lobe seizures and progressive aphasia in a 54-year-old woman. Initially, MRI volumetry of the temporal lobes showed significant left cortical thickening corresponding to an elevated amino-acid uptake in the left temporoparietal
Allergic rhinitis is the main symptom of pollinosis, relieved by non-specific treatment universally. This study aimed to find the changes of serum metabolites between the seizure and remission periods of pollinosis and provide assistance in the diagnosis and/or
