Recently, high-resolution (HR) intracranial vessel wall
imaging is used to demonstrate intracranial arterial
wall abnormality. The aim of this study was to evaluate
atherosclerotic plaque with contrast enhancement on the
middle cerebral arteries (MCA) in patients with
unilateral noncardiogenic acute ischemic stroke.
Twenty-eight patients were included in this study. MRI
was performed at 3.0 T. The patterns of enhancing wall
thickening of the ipsilateral and contralateral MCA were
compared. All of ipsilateral MCA and most of
contralateral MCA showed enhancing wall thickening,
however, the burden and involved site was different
between ipsilateral and contralateral MCA.
