Neuroimaging

Magnetic resonance imaging (MRI) allows to visualize and quantitatively assess brain morphology. Recently, various new MRI methods have been developed that provide important new insights into the morphological alterations occurring in neurodegenerative diseases. Voxel-based morphometry (VBM) is helpful in comprehensively assessing anatomical differences of grey and white matter throughout the brain in an automated and unbiassed way. Voxel-based relaxometry (VBR) takes into account the additional information obtained from T2 relaxometry. Diffusion tensor imaging (DTI) is particularly useful in studying white matter fiber tracts.

We apply various MRI morphometric methods to patients with neurodegenerative disease, in particular multiple system atrophy (MSA), spinocerebellar atrophies (SCA) and myotonic dystrophy. Correlation of morphological parameters with clinical and performance measures provides a better understanding of the brain structural changes underlying neuronal dysfunction in these disorders. We are also interested in evaluating the potential of brain structural MRI as an outcome measure in clinical trials.
