Summary
Identifying the central sulcus is crucial for neurosurgery. This study presents direct and indirect methods for locating the central sulcus, aiding in surgical planning and anatomical understanding.
Area of Science:
- Neurosurgery
- Radiology
- Neuroanatomy
Background:
- The central sulcus is a critical landmark in brain anatomy.
- Accurate identification is essential for neurosurgical procedures and research.
- Previous methods may lack precision or applicability in all cases.
Purpose of the Study:
- To present reliable methods for identifying the central sulcus.
- To evaluate the efficacy of direct and indirect identification techniques.
- To provide anatomical markers for precise localization.
Main Methods:
- Direct identification using sulcal visualization on CT and MRI scans.
- Analysis of sulcal morphology, including the superior frontal sulcus and precentral sulcus.
- Indirect identification by transferring information from sagittal to axial views using skull landmarks.
Main Results:
- Direct method is effective with good sulcal visualization (90% CT, 50% MRI).
- Key morphological signs for direct identification were detailed.
- Indirect method offers a less precise alternative when direct visualization fails.
Conclusions:
- Both direct and indirect methods can reliably identify the central sulcus.
- The direct method, utilizing specific anatomical landmarks, offers higher precision.
- These methods enhance anatomical localization for clinical and research applications.
