A combination of functional Magnetic Resonance Imaging (fMRI), Diffusion Tensor Imaging (DTI) and Voxel Based Morphometry (VBM) used together can give better information of the language lateralization than using a single technique alone.The combination of these three techniques provides an opportunity to study the relationship between brain structure and function. In patients especially small children who fail to perform the fMRI language tasks, the presurgical lateralization of language function may be done using diffusion tractography & volumetry of specific cortical structures.
