Neuronavigation: principles, clinical applications and potential pitfalls

Localization of brain lesions and prevention of damage to vital structures are important in operation of brain pathologies. Despite development of many techniques including angiography, MRI, sonography, and frame base stereotaxy, a more accurate localizing technique is still needed (1, 2). A step forward to achieve this goal is to develop a navigation system. In this manuscript, we explained some clinical applications, advantages, and disadvantages of navigation system and tried to have a short glimpse on its future.
