Area of Science:

  • Neurology
  • Radiology
  • Medical Imaging

Background:

  • Epilepsy diagnosis relies on understanding its underlying histologic substrates.
  • Symptomatic epilepsy presents diverse etiologies requiring accurate identification.

Purpose of the Study:

  • To review the magnetic resonance imaging (MRI) appearance of epilepsy's histologic substrates.
  • To discuss the clinical role of MRI in managing symptomatic epilepsy.

Main Methods:

  • Review of MRI findings correlated with histologic substrates of epilepsy.
  • Analysis of clinical applications of MRI in epilepsy management.

Main Results:

  • MRI effectively characterizes morphologic substrates of epilepsy, including tumors, neuronal migration disorders, vascular malformations, and sclerosis.
  • MRI is the most sensitive and specific noninvasive technique for identifying these substrates.
  • MRI has significantly impacted epilepsy patient management over the past decade.

Conclusions:

  • MRI plays a vital role in identifying surgical candidates, planning surgeries, and determining prognosis in epilepsy.
  • The advanced imaging capabilities of MRI allow for the detection of subtle cortical abnormalities.
  • MRI has revolutionized the diagnostic and therapeutic approach to symptomatic epilepsy.
