Intracranial atherosclerosis is one of the most
important causes of ischemic stroke and transient
ischemic attack (TIA). In the recent years, several
intracranial vessel wall imaging techniques using (ultra)high-field
magnetic resonance imaging (MRI) have emerged for the
evaluation of atherosclerotic vessel wall lesions.
However, a thorough correlation of MRI results of
intracranial plaques with histopathology is still
lacking. Therefore, a multi-contrast
ultrahigh-resolution MRI protocol at 7T was developed
for ex vivo quantitative intracranial atherosclerotic
plaque characterization. Together with the results of
the corresponding histological data, a proper
correlation of the MRI findings with the underlying
pathology may be performed.
