[Research Progress on Medical Imaging and New Ultrasound Techniques for Assessing the Degree of Carotid Artery Stenosis].

Abstract

The paper summarizes the imaging evaluation methods for assessing the degree of carotid artery stenosis and analyzes the unique advantages and limitations of various imaging techniques in vascular imaging based on existing guidelines and consensus. The paper focuses on reviewing the clinical applications of several novel ultrasound technologies, including the use of advanced hemodynamic parameters such as blood flow dispersion (Tur index) and wall shear stress (WSS). Carotid artery stenosis is closely associated with cardiovascular disease. Although non-invasive and radiation-free ultrasound technology has certain limitations in diagnostic accuracy to a certain extent, with the continuous emergence of advanced functions such as ultrasound hemodynamics and vascular elasticity, the combination of multi-modality and multi-parameter ultrasound is expected to become an important method for efficient diagnosis of arterial stenosis in the future.
