- Deep Medullary Vein Integrity and Relationships with Small Vessel Disease and Interstitial Diffusivity Measures in Patients with a Recent Small Subcortical Infarct
In this retrospective observational study, the authors assessed how DMV integrity relates to MRI-based SVD severity markers and glymphatic function assessed by DTI measures in patients with a recent small subcortical infarct. DMV disruption demonstrated a weak association with SVD, influenced by confounding factors, and a strong relationship with microstructural WM integrity and free water content, suggesting the potential involvement of extracellular fluid in mechanisms leading to vein disruption.
- A Comparative Study of CT Perfusion Postprocessing Tools in Medium/Distal Vessel Occlusion Stroke
This retrospective single-center cohort study investigated the discrepancy of 2 widely used postprocessing tools (Syngo.via and RapidAI) for CTP in patients with medium/distal vessel occlusion (MDVO) stroke. The 2 postprocessing tools were discordant on the volume and the location of perfusion deficit in isolated MDVO as well as the volume of potentially salvageable penumbra. As such, this questions whether infarct core size or penumbra volume should routinely be used to identify candidates for MDVO thrombectomy.
