Concepts of myelin and myelination in neuroradiology.
Until the advent of MR imaging, knowledge of the structure of myelin and the process of myelination were of little importance to the neuroradiologist. Other than some mild changes in the attenuation of white matter, myelination resulted in no significant alterations of CT (1) or sonographic studies. MR studies, on the other hand, have been increasingly used for pediatric brain imaging. MR imagi...
متن کاملMagnetic resonance imaging demonstrates incomplete myelination in 18q- syndrome: evidence for myelin basic protein haploinsufficiency.
Magnetic resonance imaging (MRI) and MRI relaxometry were used to investigate disturbed brain myelination in 18q- syndrome, a disorder characterized by mental retardation, dysmorphic features, and growth failure. T1-weighted and dual spin-echo T2-weighted MR images were obtained, and T1 and T2 parametric image maps were created for 20 patients and 12 controls. MRI demonstrated abnormal brain wh...
متن کاملDirect magnetic resonance detection of myelin and prospects for quantitative imaging of myelin density.
Magnetic resonance imaging has previously demonstrated its potential for indirectly mapping myelin density, either by relaxometric detection of myelin water or magnetization transfer. Here, we investigated whether myelin can be detected and possibly quantified directly. We identified the spectrum of myelin in the spinal cord in situ as well as in myelin lipids extracted via a sucrose gradient m...
متن کاملMyelin-Oligodendrocyte Glycoprotein Antibodies Spectrum Disorders
Myelin-Oligodendrocyte Glycoprotein (MOG) is an adhesive molecule responsible for myelin sheath structural integrity and maintenance. Patients with spectrum of inflammatory demyelinating disease particularly in central nervous system are reported to have antibodies against this protein. Diseases such as multiple sclerosis, clinically isolated syndrome, neuro-myelitis optica (NMO) spectrum disor...
متن کاملCholesterol in myelin biogenesis and hypomyelinating disorders.
The largest pool of free cholesterol in mammals resides in myelin membranes. Myelin facilitates rapid saltatory impulse propagation by electrical insulation of axons. This function is achieved by ensheathing axons with a tightly compacted stack of membranes. Cholesterol influences myelination at many steps, from the differentiation of myelinating glial cells, over the process of myelin membrane...
