Intraoperative CT scans improve neurosurgery by enabling real-time adjustments during tumor removal and deep brain electrode placement, leading to better surgical outcomes.

Area of Science:

  • Neurosurgery
  • Medical Imaging
  • Surgical Technology

Background:

  • Advancements in computed tomography (CT) systems have led to the development of intraoperative CT.
  • Intraoperative CT has been adopted in neurosurgical centers to enhance lesion removal and surgical outcomes.

Purpose of the Study:

  • To evaluate the utility of intraoperative CT (iCT) in neurosurgical procedures.
  • To assess the impact of iCT on tumor resection and deep brain electrode placement.

Main Methods:

  • A mobile CT scanner (Philips Tomoscan M) was utilized for intraoperative evaluation.
  • iCT was employed during 27 tumor resections and 23 deep brain electrode positioning procedures.
  • Postoperative CT scans were performed on 198 patients in the recovery room.

Main Results:

  • Incomplete tumor removal was identified in 23 out of 27 cases (85%) using real-time iCT evaluation.
  • Accurate positioning of stereotactic electrodes was confirmed in 21 out of 23 cases (91%).

Conclusions:

  • Intraoperative CT scanning is a valuable tool in neurosurgery.
  • iCT facilitates modifications to neuronavigation planning.
  • It provides crucial information for optimizing tumor removal, managing hemorrhagic complications, and ensuring accurate deep brain electrode placement.
