First‐Trimester Crown‐Rump Length and Large for Gestational Age Newborns: What Correlation?

Journal of Clinical Ultrasound, EarlyView.
Our research found for the first time that uneventful pregnancies with LGA neonates are characterized by larger than expected CRL at the first trimester. CRL is one of the new markers that can be used to early identify fetuses at risk of increased fetal growth.

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 ...

Most Small Cerebral Cortical Veins Demonstrate Significant Flow Pulsatility: A Human Phase Contrast MRI Study at 7T

Frontiers in Neuroscience, 2020
Phase contrast MRI (pcMRI) has been used to investigate flow pulsatility in cerebral arteries, larger cerebral veins, and the cerebrospinal fluid (CSF). Such measurements of intracranial pulsatility and compliance are beginning to inform understanding of

Clustering of Cerebral Microbleeds in Cerebral Amyloid Angiopathy: A Flow Territory‐Based Analysis

Journal of Magnetic Resonance Imaging, EarlyView.
ABSTRACT Background Cerebral microbleeds (CMBs) are a key imaging marker of cerebral amyloid angiopathy (CAA), but their individual spatial distribution and potential clustering remain poorly understood. Purpose This study assessed whether CMBs exhibit patient‐specific, flow territory‐based clustering in sporadic (sCAA) and Dutch‐type hereditary CAA (D‐

Comparison of 3‐Dimensional Ultrasound and Computed Tomography for Imaging of Abdominal Aortic Aneurysms

Journal of Ultrasound in Medicine, EarlyView.
Objectives Three‐dimensional ultrasound (3D US) is emerging as a novel imaging method for abdominal aortic aneurysms (AAAs) as it creates a low‐cost 3D AAA overview without harmful radiation and nephrotoxic contrast agents, as opposed to conventional imaging. 3D US can be used with a non‐nephrotoxic contrast agent (3D‐CEUS) for lumen delineation.

Flow 2.0: A Standardized Toolbox for Real‐Time Phase‐Contrast MRI of Neurofluid Dynamics

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Real‐time phase‐contrast MRI (RT‐PC) enables continuous quantification of physiological flow dynamics across multiple temporal frequencies, but its broader application is limited by complex and fragmented post‐processing workflows.

Median Effective Volume of 0.2% Ropivacaine for Ultrasound‐Guided Axillary Brachial Plexus Block in Children Aged 6–10 Years: A Prospective Dose‐Finding Study Using Up‐and‐Down Sequential Allocation

Pediatric Discovery, EarlyView.
Purpose: This study aimed to determine the median effective volume (EV50) of 0.2% ropivacaine for ultrasound‐guided axillary brachial plexus block (ABPB) in children aged 6–10 years, using the Dixon up‐and‐down method. The EV50 was 0.350 mL/kg (95% CI: 0.197–0.362 mL/kg), calculated by isotonic regression and bootstrapping.
