Summary
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.
