Progress on the Application of High-Resolution Vessel Wall Imaging in Patients with Ischemic Stroke
High-resolution vessel wall imaging(HR-VWI)is an innovative diagnostic technology for cerebrovascular diseases.Compared with the conventional imaging examinations like CT,MRA,and DSA,which can only observe the degree of luminal stenosis,this technology can detect the structural alterations in the vessel wall early before the occurrence of luminal stenosis,and provide clear observations of the biological morphology of plaques,including the size/thickness of the plaques,intraplaque hemorrhage,lipid-rich necrotic cores,and ruptured fibrous caps.Consequently,it substantially augments the etiological diagnosis rate of ischemic stroke.This paper illustrated the importance of HR-VWI technology in the prevention and treatment of ischemic stroke through presenting the application of HR-VWI technology in atherosclerotic ischemic stroke,cerebral small vessel disease,cervicocerebral artery dissection,and other special causes of ischemic stroke.
