The post Diffusion Tensor Imaging Assessment of the Epileptogenic Zone in Children with Localization-Related Epilepsy appeared first on AJNR News Digest.ĭetection of Mesial Temporal Lobe Hypoperfusion in Patients with Temporal Lobe Epilepsy by Use of Arterial Spin Labeled Perfusion MR ImagingĬomplex partial seizures, often arising in the temporal lobe, are the most common etiology of medically intractable acquired epilepsy in adults, but seizure foci can be difficult to lateralize. However, the success of epilepsy surgery is. The post Multisection Proton MR Spectroscopy for Mesial Temporal Lobe Epilepsy appeared first on AJNR News Digest.ĭiffusion Tensor Imaging Assessment of the Epileptogenic Zone in Children with Localization-Related EpilepsyĮpilepsy surgery may be the only treatment option to achieve seizure freedom in patients with medically refractory localization-related epilepsy, also known as focal epilepsy. Proton MR spectroscopy (MRS) studies of patients with temporal lobe epilepsy (TLE) have consistently shown reduced concentration of the neuronal marker N-acetylaspartate (NAA) in the medial temporal lobe ipsilateral to the. Multisection Proton MR Spectroscopy for Mesial Temporal Lobe Epilepsy The post 3T MRI Quantification of Hippocampal Volume and Signal in Mesial Temporal Lobe Epilepsy Improves Detection of Hippocampal Sclerosis appeared first on AJNR News Digest. Mesial temporal lobe epilepsy (MTLE) associated with hippocampal sclerosis (HS). Surgical treatment, with removal of the epileptogenic zone, remains the best therapeutic option for patients with pharmacoresistant focal epilepsies.
