This study introduces a novel technique for precisely locating resected brain tissue during epilepsy surgery using imaging-guided surgery (IGS) and standard brain space registration. This method aids in correlating patient outcomes with tissue characteristics and anatomical locations.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Epilepsy Research

Background:

  • Imaging-guided surgery (IGS) is crucial in neurosurgery for localizing brain structures.
  • Accurate localization of resected tissue in epilepsy surgery is vital for correlating outcomes with clinical and pathological data.

Purpose of the Study:

  • To develop and validate a technique for coregistering intraoperative landmarks with pre- and postoperative scans and standard brain space (MNI).
  • To enable precise localization and identification of resected tissue anatomy and Brodmann areas (BAs) in epilepsy surgery patients.

Main Methods:

  • Collected tissue samples from 21 epilepsy patients undergoing surgery.
  • Downloaded intraoperative localization coordinates from IGS systems.
  • Transformed patient-specific tissue landmarks into Montreal Neurological Institute (MNI) standard space for BA identification.

Anteromesial Temporal Lobectomy for Medically Intractable Temporal Lobe Epilepsy: An Operative Study

Published on: August 15, 2025

Main Results:

  • Successfully identified anatomical locations of resected tissue in all patients.
  • Determined Brodmann areas (BAs) for resected tissue in 17 out of 21 patients.
  • Encountered challenges in coregistering abnormal brain anatomy in the remaining patients.

Conclusions:

  • The developed coregistration and landmark tracking technique enables precise localization of resected epilepsy tissue.
  • Identification of Brodmann areas (BAs) for resected regions enhances understanding of patient outcomes.
  • This method improves patient safety and facilitates research by linking imaging data with tissue characteristics.
