Intérêts de l'IRM dans la prise en charge des syndromes parkinsoniens

Parkinsonian syndromes are a major cause of disability in the elderly. MRI has a key role in the management of the patient. Usually normal in Parkinson disease, conventional MRI may show abnormalities related to neurodegenerative diseases (multi-systemic atrophy, progressive supra-nuclear palsy…) or secondary to numerous disorders such as hypoxia, metabolic or hereditary diseases. In clinical research, advances MRI techniques including spectroscopy, diffusion and functional MRI provide anatomo-functional and metabolic data useful to investigate pathophysiology.
