Resumo: | The authors describe their experience with three-dimensional (3D) MRI reconstructions of the cerebral cortex in neurosurgical planning of cortical and subcortical lesions. The majority of the lesions were located on the cerebral hemispheres; there were also few cases of posterior fossa lesions. The authors selected three clinical cases to demonstrate the interest of 3D MRI. The authors describe another image processing method based on the three dimensional models obtained by using Curvilinear Multiplanar Reformatting (CMR) for the identification of subtle focal dysplastic lesions in patients with epilepsy. The advantages and disadvantages of those 3D MRI reconstructions methods are discussed and a comparison with conventional cross-sectional images is mentioned. The main disadvantages are the raw data relative to long acquisition time and the difficulty in sometimes establishing the cleavage plane between the cortex and extra-axial structures (e.g. young patients; lesions with great mass effect; lesions ventrally located in the cerebral lobes). In conclusion, the 3D MRI reconstructions of the cerebral cortex reveal additional information to conventional cross-sectional images and permit a precise location of the lesions. This is essential in some circumstances for neurosurgical planning and strategy, improving neurosurgical performance and patient outcome. |
