Evaluation of New Diagnostic Methods of Cardio-embolic Related (Atrial Fibrillation) Cerebral Infarction

Evaluation of New Diagnostic Methods of Cardio-embolic Related (Atrial Fibrillation) Cerebral Infarction

The aim of the study is to estimate the contribution of abdominal imaging by magnetic resonance Imaging (MRI) and abdominal scanner in the detection of subdiaphragmatic infarction associated to the atrial fibrillation in the cerebral infarction.

Inclusion Criteria:

• Patient over 18
• Patient having a CHADS-VAsc Score ≥ 2;
• Patient hospitalized for a secondary established ischemic accident in an atrial fibrillation not anticoagulated (INR<2 and/or receiving antiplatelet (aspirin, clopidogrel)) for less than 14 days;
• Patient affiliated to a national insurance scheme or beneficiary
• Patient having given a written consent

Exclusion Criteria:

• Patient presenting cognitive disorders incompatible with the planned examinations (MRI / SCANNER).
• Pacemaker or implantable defibrillator, or other contraindication in the MRI (metallic eye brightness, intra cerebral clip).
• Contraindication in injected scanner.
• Current pregnancy
