Optimization of pseudo‐continuous arterial spin labeling for brain perfusion imaging in the intraoperative setting

open access: yesMagnetic Resonance in Medicine, Volume 95, Issue 2, Page 1123-1134, February 2026.
Abstract Purpose Pseudo‐continuous arterial spin labeling (PCASL) efficiency during intraoperative MRI is degraded due to large field inhomogeneities observed in some patients and lower arterial blood velocities induced by anesthesia. The purpose of this work was to maximize labeling efficiency during intraoperative MRI by optimizing PCASL parameters ...

Deep Vein Thrombosis in Critically Ill Patients With COVID‐19 Pneumonia

open access: yesJournal of Ultrasound in Medicine, Volume 45, Issue 1, Page 155-170, January 2026.
Objectives The risk of major venous thromboembolism (VTE) among patients with COVID‐19 is high but varies with disease severity. Estimate the incidence of lower extremity deep venous thrombosis (DVT) in critically ill hospitalized patients with COVID‐19, validate the Wells score for DVT diagnosis, and determine patients' prognosis.

Restrictive Versus Standard Intravenous Fluid Therapy and Endothelial Glycocalyx Shedding in ICU Patients With Septic Shock—A Preplanned Sub‐Study of the Randomized CLASSIC Trial

open access: yesActa Anaesthesiologica Scandinavica, Volume 70, Issue 1, January 2026.
ABSTRACT Shedding of the endothelial glycocalyx may be a pathophysiological mechanism in septic shock, to which intravenous (IV) fluid therapy may contribute. We aimed to investigate the effects of restrictive versus standard IV fluid therapy on glycocalyx shedding in adult intensive care unit (ICU) patients with septic shock.
