Introduction: Hemorrhagic transformation (HT) is a severe complication in patients with acute ischemic stroke due to large vessel occlusion (AIS-LVO) after endovascular treatment (EVT). We hypothesize that asymmetry of the internal cerebral veins (ICVs) on baseline CT angiogram (CTA) may serve as an adjunctive predictor of HT.
Methods: We conducted a study on consecutive AIS-LVO patients from November 2020 to April 2022.

Introduction: Positive end-expiratory pressure (PEEP) and prone positioning can improve gas exchange by promoting uniform lung aeration. However, elevated ventilation pressures may increase intracranial pressure (ICP) and disrupt cerebral autoregulation. This study investigated the effects of PEEP on ICP and cerebral autoregulation in a porcine model with healthy lungs and normal ICP, comparing prone and supine positions.

Background: Brain temperature signifies the thermal homeostasis of the tissue, and may serve as a marker for neuroprotective therapy. Currently, it remains challenging to map the human brain temperature with high spatial resolution. The thermal dependence of chemical exchange saturation transfer (CEST) effects of endogenous labile protons may provide a promising mechanism for the absolute brain temperature imaging.

Our study aimed to investigate vertebral bone marrow perfusion using dynamic contrast-enhanced (DCE) MRI with a pharmacokinetic model. We also measured possible changes in water and fat content and bony trabeculae using T2* quantification, MR spectroscopy (MRS), and microcomputed tomography (μCT).

Background: Intravenous antihypertensivedrugs are commonly used in acute care settings, yet their impact on cerebral blood flow (CBF) remains uncertain.
Methods: A systematic review and meta-analysis of 50 studies evaluated the effects of commonly used i.v.
