Efficacy of high-resolution cone-beam CT in the evaluation of carotid atheromatous plaque

摘要

Introduction A major disadvantage of carotid artery stenting (CAS) is the high incidence of perioperative cerebral embolism. Cerebral embolism after CAS is associated with soft plaque. Currently, higher spatial resolution imaging can be obtained with cone-beam CT (CB-CT). The correlation between the degree of contrast enhancement of the vasa vasorum (VV) on CB-CT and the vulnerability of plaque in terms of risk factors for CAS was evaluated.
