Objective

Preoperative localization of the brain lesions in relation to the gyri and to function-related cortex by curved multiplanar reconstruction.

Methods

Thirty patients with diverse brain tumors in close topical relation to the central sulcus were examined. Performance of high volumetric structural imaging (3D-TFE) and curved multiplanar reconstruction with a standard software was studied. The images were compared with preoperative functional MR-imaging of the patients.

Results

The curved multiplanar reconstruction produced a flat map of the brain surface, with a very good comparison of the surfaces of the two hemispheres, a reliable and reproducible detection of the central sulcus and the gyri and a better localization of the lesions within or adjacent to eloquent brain regions, which were identified with funtional MRI. We named the curved multiplanar reconstrucion of the brain surface the Mercator projection.

Conclusions

The Mercator Projection is an easily reproducible method to identify brain lesions in relationship to the sulci and gyri and gives helpful information concerning the topical imaging of the lesions and the extent of resection.
