Background: Atherosclerotic plaque locations in the carotid bulb increasingly have been found to be associated with patterns of ischemic lesions and progression. However, occurrence is a complex process. We aimed investigate characteristics geometric hemodynamic parameters among patients body apical plaques identify mechanism formation location. Methods: Consecutive single stenosis (50–99%) were enrolled retrospectively. Patients divided into groups based on Plaque location identified...

The difficulty of recanalization for intracranial atherosclerosis–related large vessel occlusion (ICAS-LVO) is closely related to the severity stenosis. This study sought investigate characteristics enhancement based on high-resolution magnetic resonance imaging (HR-MRI) so as judge Sixty-two patients with symptomatic ICAS-LVOs who underwent endovascular treatment were prospectively recruited HR-MRI (33 severe stenosis and 29 without). diagnostic agreements in locating segments assessed...

Aim: This study aimed to predict progression-free survival (PFS) in patients with early glottic cancer using radiomic features on dual-energy computed tomography iodine maps. Methods: Radiomic were extracted from arterial and venous phase maps, risk scores determined by univariate Cox proportional hazards regression analysis least absolute shrinkage selection operator tenfold cross-validation. The Kaplan-Meier method was used evaluate the association between PFS. Results: Patients stratified...

High-resolution vessel wall imaging (HR-VWI) can provide information about exact occluded length, etiology, and the presence of intraluminal thrombus or residual cavity.To investigate extra value HR-VWI in screening patients with chronic internal carotid artery occlusion (CICAO) for recanalization suitability comparison digital subtraction angiography (DSA).We retrospectively reviewed who underwent endovascular no signal on magnetic resonance (MRA) whose both preoperative DSA data were...
