Article Synopsis
- The study explores the link between specific types of dangerous plaques (cCAPs) in carotid arteries and the risk of ischemic stroke, focusing on the role of blood flow dynamics.
- Researchers examined 49 patients with mild internal carotid artery (ICA) stenosis using advanced imaging techniques (4D flow-MRI) to measure parameters like wall shear stress (WSS) and oscillatory shear index (OSI).
- Findings revealed that higher WSS at certain points in the artery was significantly associated with the presence of cCAPs, suggesting that blood flow patterns could be important for identifying stroke risk.
Article Synopsis
- Doctors are trying to figure out who is at the highest risk of having another stroke after a TIA or minor stroke by looking at different factors, mainly how blocked someone's carotid arteries are.
- A new tool called the IMPROVE model has been created to better predict stroke risk by using information from MRI scans and other factors like age and sex.
- This model has been tested successfully and can help doctors decide who might need surgery to prevent future strokes.

Background: Carotid artery atherosclerosis is highly prevalent in the general population and is a well-established risk factor for acute ischemic stroke. Although the morphological characteristics of vulnerable plaques are well recognized, there is a lack of consensus in reporting and interpreting carotid plaque features.
Objectives: The aim of this paper is to establish a consistent and comprehensive approach for imaging and reporting carotid plaque by introducing the Plaque-RADS (Reporting and Data System) score.
Introduction: Complicated carotid artery plaques (cCAPs) are associated with an increased risk of rupture and subsequent stroke. The geometry of the carotid bifurcation determines the distribution of local hemodynamics and could thus contribute to the development and composition of these plaques. Therefore, we studied the role of carotid bifurcation geometry in the presence of cCAPs.
