Background: Intracranial atherosclerosis (ICAS) is the leading cause of ischemic stroke in Asians and the recurrent rate remains high despite the optimal medical treatment. This study aimed to confirm that follow-up high-resolution magnetic resonance imaging (hrMRI) provided essential values in predicting subsequent cerebral ischemic events in patients with ICAS.
Methods: Patients with moderate to severe stenosis in the middle cerebral artery (MCA) defined by magnetic resonance (MRA) or computed tomography angiography (CTA) were recruited from three centers retrospectively.
Background: Radiotherapy has been crucial in prostate cancer treatment. However, manual segmentation is labor intensive and highly variable among radiation oncologists. In this study, a deep learning based automated contouring model is constructed for clinical target volumes (CTVs) of intact and postoperative prostate cancer.
View Article and Find Full Text PDFAutonomous vehicles (AVs) have the potential to revolutionize transportation safety and mobility, but many people are still concerned about the safety of AVs and hesitate to use them. Here we survey 4112 individuals to explore the relationship between knowledge and public support for AVs. We find that AV support has a positive relationship with scientific literacy (objective knowledge about science) and perceived understanding of AV (self-assessed knowledge).

This study was focused on assessing whether plaque enhancement features contribute to culprit plaque identification and further risk stratification.
Methods: We retrospectively studied patients who experienced an acute ischaemic stroke and transient ischaemic attack due to intracranial atherosclerosis from 2016 to 2022.
