Technologies and Strategies for Metabolic and Molecular Imaging With Hyperpolarized MRI

open access: yesJournal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Conventional Magnetic Resonance Imaging (MRI) offers limited sensitivity for direct metabolic and molecular imaging using non‐proton nuclei due to low thermal nuclear spin polarization. Hyperpolarization (HP) technologies increase nuclear spin polarization by several orders of magnitude, overcoming this limitation to enable in vivo studies of ...

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

open access: yesJournal of Ultrasound in Medicine, EarlyView.
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.
