Background And Purpose: The development of high-resolution magnetic resonance imaging (HR-MRI) has enabled submillimeter-level evaluation of intracranial artery plaque and luminal thrombus. We sought to investigate the value of HR-MRI in assessing the pathogenesis of acute intracranial artery thrombus.
Methods: We examined the presence of intracranial thrombus on three-dimensional T1-weighted HR-MRI in acute ischemic stroke patients with intracranial artery occlusion on magnetic resonance angiography.

Background: Intracranial atherosclerotic stenosis (ICAS) is one of the leading causes of stroke worldwide. Current diagnostic evaluations and treatments remain insufficient to assess the vulnerability of intracranial plaques and reduce the recurrence of stroke in symptomatic ICAS. On the other hand, asymptomatic ICAS is associated with an increased risk of cognitive impairment.

However, whether upstream artery geometries influence downstream atherosclerosis remains unclear. We aimed to investigate whether carotid artery geometries were associated with middle cerebral artery (MCA) atherosclerosis.

He had left thalamus and cerebellum infarction 6 months ago, and left occipital lobe infarction 2 years ago. 68Ga-FAPI PET/MR showed focal uptake along the low segment of the basilar artery.

Based on the three-dimensional T1-weighted high-resolution magnetic resonance imaging (3DT1 HR-MRI) data of patients with low-grade stenotic (<50%) atherosclerotic middle cerebral artery (MCA) and subjects with normal MCA, we built a three-dimensional reconstructed WSS model by computational fluid dynamics (CFD) technique. Three-dimensional registration of the CFD model to the HR-MRI was performed with projections based on the resolution and thickness of the images.

Despite the proliferation of mobile apps, few studies have evaluated the apps that are available to the millions of people with diabetes in China.
Objective: This study aimed to conduct a systematic search of Chinese mobile apps for diabetes self-management and to evaluate their quality, functionality, and features by using validated rating scales.
Background: This study analyzes the demographics of patients affected by Takayasu arteritis (TA). The study further explores the correlation and other contributory factors to the regional differences between the ratios of females to males (sex ratio).
Methods: This was a retrospective study using 1,011 clinical cases diagnosed with TA (as per 1990 American College of Rheumatology criteria) between 1982 and 2015 collected from the Peking Union Medical College Hospital (PUMCH) database.
