In the context of MRI-guided stereotaxy a new stereotaxic atlas of the human thalamus was developed in order to improve anatomical definition and precision in the prediction of the exact location of thalamic targets. It is based on multiarchitectonic parcellation (Nissl, myelin, calcium-binding proteins). Sagittal atlas data were digitized and registered together with 3D MRI data sets. In a coa...

BACKGROUND A craniocerebral trauma caused by firearms is a complex injury with high morbidity and mortality. One of the most intriguing and controversial part in their management in salvageable patients is the decision to remove the bullet/pellet. A bullet is foreign to the brain and, in principle, should be removed. Surgical options for bullet extraction span from conventional craniotomy, thro...

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 so...
