Summary

To date except for the larger striato-pallidal complex, there are no reliable imaging markers of small deep nuclei. Major improvement of the spatial resolution resulting from the use of ultra-high field MRI systems offers new perspectives of imaging of these deep structures.

We will use the new contrast mechanisms available in data acquired with ultra-high field MR systems (7T) as well as the most recent high angular diffusion imaging techniques in order to characterize the cytoarchitectonics of the deep brain structures and brainstem lesions in parkinsonian syndromes (with special interest in substantia nigra (SN) pathology and nigro-striatal fiber pathways; subthalamic nucleus (STN), red nucleus (RN), oculomotor structures (involved in PSP); pedonculo-pontine nucleus (involved in gait and posture control disorders) and the locus sub-coeruleus area (implicated in sleep disorders) The optimized MR sequences at 7T will be adapted and validated at 3T (on a more clinically oriented MRI approach).

The clinical goal of the project (via the characterization of deep brain structures) is the detection of new neuroimaging markers of neuronal lesions in PD. These biomarkers will be used to create a diagnostic tool at early stage of the disease that could be correlated to clinical signs such as gait disorders and help to identify predictive factors. In addition, this could contribute to establish an adequate therapeutic strategy (as for example with deep brain stimulation).
