A Sub‐Microsecond Switch Enabling SWIFT 23Na Imaging at 10.5 T

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable sodium SWIFT imaging, which is a zero‐echo time imaging technique, at ultra‐high magnetic fields through the development of custom electronics hardware, and to showcase this capability with in vivo imaging results. Methods The custom hardware developed consists of a high‐speed optical trigger with 10 ns resolution, an in‐bore

Intraoperative Cardiac Events During Pediatric Cardiac Magnetic Resonance Imaging Under Anesthesia: A Retrospective Cohort Study

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Children with congenital heart disease (CHD) frequently undergo cardiac magnetic resonance imaging (MRI) under anesthesia. Although these procedures lack surgical stimulus, patients remain physiologically vulnerable, and the incidence of perioperative cardiovascular instability in this setting is poorly defined.

Respiratory profile of pediatric patients undergoing hematopoietic stem cell transplantation studied by oscillometry – A TRANSPIRE cohort

open access: yesPediatric Investigation, EarlyView.
These are results from a multi‐center collaboration between four large pediatric institutions, investigating baseline respiratory system function in a cohort of children undergoing hematopoietic stem cell transplantation. This manuscript proposes respiratory oscillometry as a novel way to prospectively follow lung function in these children.

Simulation of superconducting resistive fault current limiter with magnetic field boosting using a shunt coil

open access: yes, 2001
We have investigated via simulation the quench characteristics of resistive superconducting fault current limiters (SCRFCL) based on YBCO thick film deposited on YSZ substrate.

Miyazaki Syndrome due to Ventriculoperitoneal Shunt Treatment

open access: yes, 2018
The signs and pathomechanism of Miyazaki syndrome is presented through the case of a young female patient. The patient underwent placement of a ventriculoperitoneal (VP) shunt with a pressure-adjustable valve for communicating hydrocephalus years before ...

No increased risk of spinal cerebrospinal fluid leak after spinal manipulative therapy: A retrospective cohort study

open access: yesPM&R, EarlyView.
Abstract Background Spinal cerebrospinal fluid (CSF) leaks, a rare but debilitating condition, have been described following spinal manipulative therapy (SMT) in case reports. However, the nature of the potential association between SMT and CSF leak is uncertain, and symptoms such as neck pain or headache may reflect preexisting leaks rather than ...

Reduction of shunt current in buffer-free IrMn based spin-valve structures

open access: yes, 2018
The presence of thick buffer layers in magnetic sensor devices decreases sensor sensitivity due to shunt currents. With this motivation, we produced IrMn-based spin-valve multilayers without using buffer layer.

Microbubble‐Based Ultrasound Contrast Agents in Contrast‐Enhanced Ultrasonography for Managing Portal Hypertension in Cirrhosis

open access: yesPortal Hypertension &Cirrhosis, EarlyView.
As the hepatic venous pressure gradient (HVPG) remains the current gold standard for diagnosing portal hypertension in cirrhosis, its clinical application is limited by invasiveness, high cost, and restricted availability. Given the urgent need for noninvasive techniques to dynamically monitor portal vein pressure (PVP), contrast‐enhanced ...
