Research Progress of High-resolution Magnetic Resonance Vessel Wall Imaging in the Identification of Intracranial Arterial Stenosis Etiology

Abstract

Ischemic stroke caused by intracranial arterial stenosis (ICAS) is characterized by high morbidity and mortality. Conventional clinical examination methods include transcranial Doppler ultrasound, CT angiography, magnetic resonance angiography, and X-ray digital subtraction angiography. These methods are aimed at vascular stenosis and do not show vascular wall lesions. High-resolution magnetic resonance vessel wall imaging (HR-VWI) is a new imaging method that can non-invasively display vascular wall lesions and has important value in judging the nature of ICAS lesions. In this paper, the application of HR-VWI in the identification of ICAS etiology is reviewed.
