Study Description

Brief summary:

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.

Arms and interventions

Arm Intervention/treatment
Other: Confirmed TIA
Confirmed TIA at 3 months with standardized neurological expertise
Diagnostic Test: Functional Magnetic Resonance Imaging
fMRI sequences done with motor paradigm (right and left arm), followed by resting state acquisition
Other: Confirmed non-TIA
Not-confirmed TIA at 3 months with standardized neurological expertise
Diagnostic Test: Functional Magnetic Resonance Imaging
fMRI sequences done with motor paradigm (right and left arm), followed by resting state acquisition

Outcome Measures

  • Primary Outcome Measures: 1. Blood-Oxygen-Level Dependent signal [ Time Frame: 24 hours after symptoms onset ]
