white matter lesions (wmls) are commonly observed in strokepatients with small vessel disease (svd) and are thought toresult from a progressive, irreversible disease process followingarteriolosclerosis. in this study, we report a case of partialdisappearance of wmls 1 year after a lacunar stroke in a69-year-old man with evidence of svd. we also discuss possiblemechanisms associated with this ob...

background: volume estimation of brain is important for many neurological applications. it is necessary in measuring brain growth and changes in brain in normal/abnormal patients. thus, accurate brain volume measurement is very important. magnetic resonance imaging (mri) is the method of choice for volume quantification due to excellent levels of image resolution and between-tissue contrast. st...

Neuroimaging findings have proposed that some brain regions including the precuneus, posterior cingulate, and medial prefrontal cortex play an essential role of a structural core in the brain. Network organization endures rapid alterations in development with changes in axonal synaptic connectivity, white matter volume, and the thickness of corresponding cortical regions. Structural maturation ...

Background and Aim: The methods for detecting brain activation with fMRI, MRI provides a way to measure the anatomical connections which enable lightning-fast communication among neurons that specialize in different kinds of brain functions. Diffusion tensor imaging is able to measure the direction of bundles of the axonal fibers which are all aligned. Besides mapping white matter fiber tracts,...

introduction: multiple sclerosis (ms) is a demyelinating disease of the central nervous system (cns), affecting mostly young people at a mean age of 30 years. magnetic resonance imaging (mri) is one of the most specific and sensitive methods in diagnosing and detecting the evolution of multiple sclerosis disease. but it does not have the ability to differentiate between distinct histopathologic...

leukodystrophies are metabolic disorders of the brain, spinal cord and, in part, of the peripheral nerves that lead to degeneration of the white matter (myelin) of the brain. since mainly nerve tracts, which control voluntary movement, are embedded in myelin, patients with leukodystrophy suffer from progressive movement disorders and later also from mental deterioration. through a survey, we ca...
