Single subcortical infarction (SSI) in middle cerebral
artery (MCA) territory has been considered to be mainly
caused by lipohyalinosis or atherosclerosis. We
investigated the presence of MCA plaques in patients
with SSI using three-dimensional (3D) high-resolution
black-blood MRI imaging, and found that atherosclerosis
was more prevalent than commonly thought among patients
with SSI. Meanwhile, Ipsilateral MCA had higher
frequencies of atherosclerotic than contralateral side,
most of which were superiorly located. 3D HR-MRI can
noninvasively in vivo providing detailed information of
intracranial atherosclerotic plaques with broad coverage
in approximately 6 min and could strengthen our
comprehension of SSI mechanism.
