Functional Imaging in the Acute Phase of Transient Ischemic Attacks

Contribution of Functional Imaging to the Diagnostic and Assesment of the Acute Phase of Transient Ischemic Attacks : a Preliminary Study

The aim of the study is to find a radiological biomarker of Transient Ischemic Attacks (TIA) thanks to functional Magnetic Resonance Imaging (fMRI) done within the 24 hour after symptoms onset.

Inclusion Criteria:

• Patient admitted in for a transient neurologic deficit and suspicion of TIA of carotid circulation
• Prescription for conventionnal MRI

Exclusion Criteria:

• Contraindication to MRI
• Previous neurological disease (with lesions)
• Severe psychiatric disease
