Geometric information obtained from MRI is widely used for various applications, including voxel-based morphometry brain volume measurement, radiation therapy planning, and MRI-guided therapy.

Introduction: FDG Brain PET is a valuable paraclinical tool for presurgical assessments of patients suffering from refractory epilepsy. By the widespread accessibility of PET, recognizing the functional lesions has become a current practical method especially in preoperative evaluations of the partial epilepsy disorders. The aim of our study was to assess the impact of quantit...

Recent advancement of MRI techniques and development of new methods of image analysis have allowed us to study large neural tracts within the human brain. This is based on the principle of diffusion tensor MRI that is similar to that of diffusion-weighted imaging but takes magnitude and direction of the diffusion of water into account. Using this technique we have been able to define large neur...

Canavan disease is an autosomal recessive leukodystrophy due to accumulation of N-acetyl aspartic acid (NAA) in brain, cerebrospinal fluid (CSF), and urine characterized by early onset developmental delay, initial hypotonia progressing to hypertonia, sleep disturbance and macrocephaly. Brain magnetic resonance imaging (MRI) shows white-matter changes. The best method for diagnosis is determined...

epilepsy is an important disease with a cumulative incidence of 3% all over the life and more than half of them are started from childhood. in this study we surveyed magnetic resonance imaging (mri) findings in epileptic children and its relation with clinical and demographic findings in order to find better diagnostic and treatment modalities for these children in the future. in this cross sec...

Background: Several treatments have been proposed to control Multiple Sclerosis (MS). Fingolimod is the first oral medication for the disease that was approval by Food and Drug Administration American (FDA) since 2010 and is produced in Iran from October 2013. The aim of this study was evaluation of the effect of fingolimod on the number of brain plaque in multiple sclerosis patients before and...
