title: [CT and MR imaging in stereotaxic neurosurgery].
abstract: The combination of CT and MR examinations indicates a specific approach to the treatment of brain mass lesions. CT guided stereotaxy is sufficient for well demarcated tumors, haemorrhages and abscesses. MR guided stereotaxy is necessary to be performed in invasively growing brain tumors where explicit histological verification and localisation must be ascertained. In addition it is necessary to take into account the image deformation due to the stereotactic ring. In functional neurosurgery the MR examination visualises the anatomical structures which are needed for the ascertainment of coordinate systems landmarks in coordinate system. (Fig. 1, Tab. 1, Ref. 5.).
