Summary: This study investigated the predictive roles of plaque features, plaque number, and co-existing atherosclerosis in stroke recurrence using combined head-and-neck high-resolution vessel wall imaging. The presence of co-existing intracranial high signal on T1-weighted fat-suppressed images (HST1) and extracranial carotid atherosclerosis were identified as independent imaging predictors of stroke recurrence.

Summary: In a Chinese population, there are significant differences in carotid plaque features between men and women. Men have a higher quantity of plaques and are more prone to vulnerable atherosclerotic plaques, while women have a smaller plaque burden.

Summary: This study aimed to investigate the influence of arterial remodeling patterns on plaque characteristics and postoperative outcomes in patients with severe basilar artery stenosis. The results showed that remodeling patterns did not significantly affect the outcome of ischemic events and new ischemic cerebral lesions. However, the remodeling index was strongly associated with plaque burden, providing new insights for the evaluation of severe basilar artery stenosis.

Summary: The geometrical characteristics of the basilar artery, especially tortuosity and convexity, are independently associated with the presence, burden, and distribution of plaques in the basilar artery.

Summary: Plaque enhancement, positive remodeling, T1 hyperintensity, and surface irregularity are strong imaging biomarkers of symptomatic plaque in patients with ischemic events. Plaque enhancement remains significant in various subgroup analyses and shows stronger associations in certain circumstances. Future studies with larger sample sizes are needed to further evaluate plaque enhancement as a predictive marker for stroke recurrence.

Summary: This study evaluated the application of black-blood CT in carotid artery wall imaging and confirmed its accuracy in diagnosing stenosis rate and plaque burden of carotid artery. Black-blood CT showed good consistency with CTA and VW-MR in identifying stenosis rate and plaque burden, providing clear visualization of the artery wall, especially for patients with contraindication to MRI.

Summary: This cross-sectional study found that carotid plaque burden and vulnerable plaque features, particularly a larger lipid-rich necrotic core, may serve as effective predictors for hemodynamic instability during carotid artery stenting.

Summary: This study explored the potential risk factors for hemodynamic instability (HI) during carotid artery stenting (CAS) using magnetic resonance (MR) vessel wall imaging. The results showed that carotid plaque characteristics were associated with the occurrence of HI. The HI group had larger wall area, greater total vessel area, higher prevalence of intraplaque hemorrhage (IPH), vulnerable plaque, and larger volume of lipid-rich necrotic core (LRNC) compared to the non-HI group. Carotid LRNC volume and the presence of vulnerable plaque were significantly associated with HI.

Summary: There is a close relationship between LSAs and LIs in the basal ganglia, with the number and length of LSAs being statistically different in basal ganglias with and without LIs. The total number of LSAs and ipsilateral MCA-M1 plaques were independently related to LIs, and the mean length of LSAs was negatively correlated with the number and volume of LIs. Age, drinking history, and mean length of LSAs were associated with LI occurrence in the basal ganglia, with shorter LSAs correlated with larger volume of LIs.

Summary: This study aimed to evaluate the distribution and features of carotid artery (CA) and middle cerebral artery (MCA) plaques in patients with pial infarction (PI) and perforating artery infarction (PAI), and investigate the associations between plaque characteristics and ischemic infarction patterns. The results showed that high-risk CA plaques were significantly associated with PI, while MCA plaques involving the orifice of the perforating arteries were significantly associated with PAI. Therefore, combined intracranial and extracranial arteries imaging should be considered in the evaluation of symptomatic ischemic patients.

Summary: This study aimed to investigate the relationship between vertebrobasilar artery (VBA) calcification and plaque instability and their association with acute cerebral infarction (ACI). The study used vessel wall MRI and CT examinations to analyze the characteristics of VBA calcification and compared them between culprit and non-culprit lesions. It was found that intimal predominant calcification in vertebrobasilar atherosclerosis is associated with the likelihood of having caused acute cerebral infarction. The morphology and density of VBA calcification may provide insight into stroke risk stratification in the posterior circulation.

Summary: This study developed a model combining lesion morphological and compositional features, as well as radiomics, to predict new ipsilateral ischemic lesions (NIILs) after carotid artery stenting (CAS). The results showed that the combination of traditional features with radiomics improved the accuracy in predicting NIILs compared to traditional features alone.

Summary: This study aimed to evaluate the reproducibility of quantitative measurement and radiomic features in vessel wall MRI (VW-MRI) and assess the impact of lesion size on reproducibility. The results showed that the reproducibility of quantitative measurement increased with larger lesion thickness and volume. Additionally, radiomic features had higher reproducibility in lesions with thickness >= 2.5 mm and volume >= 50 mm(3).
