Area of Science:

  • Pediatric Neurology
  • Neuroimaging
  • Developmental Neuroscience

Background:

  • Myelination is a critical process in pediatric brain development.
  • Understanding typical myelination patterns is essential for diagnosing neurological disorders.
  • Magnetic resonance imaging (MRI) is a key tool for visualizing brain development.

Purpose of the Study:

  • To provide an image-based review of myelin evolution for pediatricians.
  • To enhance understanding of typical myelination patterns on MR imaging.
  • To serve as a quick reference for interpreting pediatric neuroimaging studies.

Main Methods:

  • Review of established literature on myelination and neuroimaging.

Magnetic Resonance Imaging

Magnetic resonance imaging (MRI) is a noninvasive medical imaging technique based on a phenomenon of nuclear physics discovered in the 1930s, in which matter exposed to magnetic fields and radio waves was found to emit radio signals. In 1970, a physician and researcher named Raymond Damadian noticed that malignant (cancerous) tissue gave off different signals than normal body tissue. He applied for a patent for the first MRI scanning device in clinical use by the early 1980s. The early MRI...

Imaging Studies IV: Magnetic Resonance Imaging

Introduction:Magnetic Resonance Imaging, or MRI, can include a specialized imaging technique of the urinary system known as Magnetic Resonance Urography (MRU). This radiation-free technique uses strong magnetic fields and radio waves to produce detailed images with the help of a computer. MRU is particularly effective for visualizing fluid-filled structures like the kidneys, ureters, and bladder.Applications of MRI in the Genitourinary SystemKidneys and Ureters: MRI detects tumors, cysts,...

Nervous Tissue: Myelin01:25

Nervous Tissue: Myelin

The myelin sheath is a multilayered lipid and protein covering that insulates the axon of a neuron, enhancing the speed of nerve impulse conduction. Axons without this sheath are referred to as unmyelinated. Two types of neuroglia, Schwann cells in the peripheral nervous system (PNS) and oligodendrocytes in the central nervous system (CNS) are responsible for producing myelin sheaths.
Schwann cells begin to form myelin sheaths around axons during fetal development. They wrap around a small...
