Summary
This study presents a modified Gildenberg technique for brain tumor biopsy, simplifying the process by eliminating the need for ScoutView imaging. The technique efficiently determines coordinates for precise tumor localization during biopsy procedures.
Area of Science:
- Neurosurgery
- Medical Imaging
- Oncology
Background:
- Gildenberg's technique is a standard for brain tumor biopsy.
- Accurate localization of brain lesions is crucial for successful biopsies.
Purpose of the Study:
- To describe a modified Gildenberg technique for brain tumor biopsy.
- To simplify the localization process and reduce procedural steps.
Main Methods:
- Marking the light beam on the scalp when the lesion is visible on the screen.
- Using radiopaque marks on drawn lines to transfer slice levels to lateral conventional X-ray for 'Z' coordinate calculation.
- Determining 'X' and 'Y' coordinates directly on the CT scanner.
Main Results:
- The modified technique eliminates the need for ScoutView imaging.
- Precise localization of the lesion is achieved through a streamlined coordinate calculation process.
Conclusions:
- The modified Gildenberg technique offers a more efficient approach to brain tumor biopsy.
- This modification simplifies localization, potentially improving procedural workflow and accuracy.
