With
the increase of cases of intracranial stenosis, the research to study the
shortcut pathways caused by carotid artery stenosis manifested by abnormal
external carotid artery perfusion image become very critical. In this
preliminary study, an upgraded tagging strategy for Vessel Encoded Arterial
Spin Labeling (VEASL) was employed to non-invasively evaluate the intra and
extracranial carotid artery supplied cerebral perfusion of healthy
volunteers, by tagging the right and left internal carotid arteries, the
external carotid artery and the vertebral arteries. Results suggested that
the proposed approach could separate the intracranial and extracranial parts
of perfusion come from external carotid artery.
