What is Neuroradiology?

Neuroradiology is a subspecialty of radiology focusing on the diagnosis and characterization of abnormalities of the central and peripheral nervous system, spine, and head and neck using neuroimaging techniques.

Neuroradiologic tests include:

  • Computed tomography(CT) scans
  • Diffuse optical imaging (DOI)
  • Event-related optical signal (EROS) scans
  • Magnetic Resonance Imaging (MRI)
  • Functional magnetic resonance imaging (fMRI)
  • Magnetoencephalography(MEG), an imaging technique used to measure the magnetic fields produced by electrical activity in the brain
  • Positron emission tomography (PET) scans
  • Single-photon emission computed tomography (SPECT)
  • Cranial ultrasound (US)
  • Functional ultrasound imaging(fUS)
  • Myelogram

Activity is prevalent in temporal lobe (bottom scans).
