Area of Science:

  • Neurology
  • Medical Imaging
  • Nuclear Medicine

Background:

  • Epilepsy diagnosis requires precise localization of the epileptogenic zone.
  • Assessing regional cerebral blood flow is crucial for understanding brain function in epilepsy.

Purpose of the Study:

  • To evaluate the utility of Single Photon Emission Computerized Tomography (SPECT) in the assessment of epileptic patients.
  • To highlight SPECT's role in identifying altered cerebral perfusion related to epilepsy.

Main Methods:

  • Utilizing radiotracers that reflect regional cerebral blood flow.
  • Applying SPECT imaging to visualize perfusion patterns during ictal and interictal periods.

Main Results:

  • SPECT successfully identifies altered perfusion in the epileptogenic zone.
