Topographical study of supratentorial brain tumors.
The topographic analysis of supratentorial brain tumors must answer the following questions: location of the tumor, its extension, its being infiltrative or well localized and especially the relationships with the main functional areas such as the speech areas, the sensori-motor area, and the visuel areas. Also the topographic analysis may help to approach the diagnosis of nature. The neuroradiological procedures include the CT, the angiography and especially the MRI in sagittal and coronal sections, with gadolinium enhancement. The anatomical accuracy is obtained using the bicommissural plane and superimposition techniques according to the Talairach's Atlas and anatomical sections and MRI superimposition with angiography. 3D volumic reconstruction is of considerable contribution for the topographic analysis of a cerebral tumor.
