Acute Effects of Smoking and Vaping on Markers of Vascular Function via Quantitative MRI

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background E‐cigarettes contribute to endothelial dysfunction, a known cause of systemic atherosclerotic disease that cannot be adequately characterized by a single physiological parameter measured at a single vascular bed. Purpose/Hypothesis Quantify and compare acute effects of smoking or vaping with tobacco cigarettes (t‐cigs), nicotinized ...

Efficacy of noninvasive hemoglobin measurement by pulse co-oximetry in neonates

Journal of Clinical Neonatology, 2020
Background: Hemoglobin (Hb) measurement is one of the most commonly performed laboratory tests in neonates. The advent of new technologies enables us to carry out noninvasive Hb measurement, without having to prick the neonate, whereby reducing iatrogenic blood loss.

Structural Covariance Analysis of Altered Brain Development in Neonates With Congenital Heart Disease After Surgery

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Brain development is altered in neonates with congenital heart disease (CHD), with well‐characterised reductions in regional brain volumes and enlargement of CSF spaces. However, perioperative morphological changes remain incompletely understood. Purpose To identify brain regions showing spatial patterns of coordinated expansion and

Optic Nerve Thickness Assessed by Ocular Ultrasonography in Obstructive Sleep Apnea

Journal of Ultrasound in Medicine, EarlyView.
Objectives Obstructive sleep apnea (OSA) has been associated with various ocular complications, yet ultrasonographic evaluation of optic nerve thickness and its relationship with nocturnal hypoxemia remains poorly understood. This study aimed to evaluate optic nerve thickness and globe dimensions using ocular ultrasonography in patients with different ...

Scalable Large Field‐of‐view 3D Photoacoustic Ultrasound Imaging With Digital Multiplexing for Human Extremities

Laser &Photonics Reviews, EarlyView.
A digitally multiplexed, large‐aperture photoacoustic and ultrasound imaging architecture is presented to overcome the fundamental limited‐view artifact inherent in conventional arrays. By significantly broadening the structural detection coverage, this scalable platform enables high‐fidelity 3D visualization of human extremities within a single ...

Phase‐Sensitive Modeling Improves Fat DESPOT Multiparametric Relaxation Mapping in Fat‐Water Mixtures

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To improve on a multiparametric technique—known as Fat DESPOT—to map the fat‐ and water‐specific R1$$ {R}_1 $$ (R1f$$ {R}_{1f} $$, R1w$$ {R}_{1w} $$), R2*$$ {R}_2^{\ast } $$, and proton density fat fraction (PDFF) by upgrading the parameter initialization and introducing explicit model sensitivity to the complex phase of the water and ...
