- Primary Outcome Measures
Name Time Method <p>The presence or absence of intracranial vessel wall abnormalities in arteries<br /><br>of the intracranial posterior circulation. Presence of atherosclerosis is<br /><br>defined as any irregularity of the arterial vessel wall.</p><br>
- Secondary Outcome Measures
Name Time Method <p>- Number of vessel wall abnormalities in the intracranial vessel wall MRI scan<br /><br>at 7.0 tesla as compared to 3.0 tesla.<br /><br>- Characteristics of intracranial vessel wall atheroma, by discriminating<br /><br>different MRI signal intensities in the vessel wall atheroma.<br /><br>- The clinical outcome measures (e.g. occurrence of vascular events, level of<br /><br>handicap, current medication) collected during follow-up.</p><br>
