About

Functional magnetic resonance imaging (fMRI) is a non-invasive imaging technique assessing neuronal activations during motor or cognitive tasks. The MRI sequences used are currently optimized for the study of cortex activations, particularly concerning the echo time (TE).Very few studies are interested in optimizing the fMRI for the study of the basal ganglia, structure implicated in many neurological diseases such as Parkinson's disease. The T2 * is a tissue parameter dependent of iron content, which differs with brain structures and probably also with age and in case of neurodegenerative disease. Optimal TE s should correspond to the T2 * of studied brain structure The primary purpose is to optimize the fMRI by a quantitative measurement of the T2* in the cortex and the basal ganglia using MRI. The secondary purpose is to study the effect of age and Parkinson's disease on T2*.

Full description

80 subjects (40 PD patients and 40 paired healthy volunteers (on sex and age)) aged 40-80 years will be included. PD patients will be recruited in the Department of Neurology of CHU of Clermont-Ferrand. Healthy volunteers will be selected in clinical trial database. This study will consist of one visit (at J0) during which subjects will undergo a MRI (a single acquisition of 40 minutes approximately). PD patients will be further questioned on their disease and will benefit from a neurological examination

Enrollment: 19 patients

Sex: All

Ages: 40 to 80 years old

Volunteers: Accepts Healthy Volunteers
