Stereotactic atlases attempt to relate the position of subcortical structures to intracranial landmarks detected by radiographic methods7,8. Considerable anatomic variability exists between individual brains. Subcortical structures have no consistent quantitative relationship to radiologically determined landmarks1,3. This variability increases in direct proportion to the distance the substructure lies from particular landmarks8.Although anterior-posterior and superior-inferior measurements from stereotactic atlases can be adjusted for variations in the intracommissural distance and thalamic height, there is no anatomical landmark detected by ordinary radiographic techniques which allows correction for medial lateral variability in the position of the internal capsule or the axial configuration of the thalamus and third ventricle. Fortunately, these structures are usually visualized on quality CT scans.
