Soon after its development, CT imaging, which provided direct visualization of neural structures, was used for stereotactic guidance. There has been progressive expansion of stereotactic methodology for image guided surgical intervention through minimally invasive corridors. Today, the development of high resolution MR imaging, multiple modes of functional imaging, advancements in three dimensional visualization of image data, and evolution in methods of tissue destruction coupled with computer assisted and computer directed surgical navigation systems, provide the neurosurgeon with the tools to perform more precise and safer surgical resections.
