Summary
This study details neuroradiological methods for calculating stereotactic brain surgery targets using computed tomography (CT) and the Riechert-Mundinger frame. It highlights the importance of pre- and post-operative CT scans for accuracy.
Area of Science:
- Neurosurgery
- Radiology
- Medical Imaging
Background:
- Advancements in neuro-imaging have improved stereotactic surgery accuracy.
- This has led to increased interest in image-guided brain surgery.
Purpose of the Study:
- To describe the neuroradiological aspects of stereotactic target calculation using computed tomography (CT).
- To illustrate patient positioning, CT techniques, and target identification with the Riechert-Mundinger (Fisher) frame.
Main Methods:
- Utilized the Riechert-Mundinger (Fisher) stereotactic frame for target coordinate calculation (x, y, z).
- Employed computed tomography (CT) for imaging and target localization.
- Demonstrated selected cases with detailed patient positioning and CT techniques.
Main Results:
- Successfully illustrated stereotactic target calculation using CT and the specified frame.
- Emphasized the critical role of pre- and post-stereotactic CT examinations for procedural success.
- Showcased patient positioning, CT technique, and target identification processes.
Conclusions:
- CT-guided stereotaxis with the Riechert-Mundinger frame provides accurate target localization for brain surgery.
- Pre- and post-operative CT scans are essential for optimizing stereotactic procedures.
- Future advancements include MR-guided stereotaxis and integrated 3D functional-anatomical maps.
