Feasibility and SNR Performance of Hyperpolarized 129Xe Gas Exchange Imaging Using a Balanced SSFP Sequence

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a balanced SSFP (bSSFP) sequence for pulmonary 129Xe dissolved‐phase imaging based on a previously described double‐echo sequence facilitating separation into red blood cell and membrane signals, to test its feasibility and compare its SNR performance and imaging results to an analogous FLASH sequence.

“Two‐For‐One”: 4D Cardiac and Pulmonary MR Imaging From a Single Acquisition Using bSTAR

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To generate 4D (3D+time) images of both the heart and lungs using a single volumetric radial free‐breathing bSSFP dual echo acquisition (bSTAR) with two image reconstructions within a single pipeline deployed inline at 0.55 and 1.5 T.

Image‐Derived Volumetry During Forced Expiration Using a 3D Fermat Looped, Orthogonally Encoded Trajectory

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To enable MRI‐based nongated 3D depiction of forced expiration with both high spatio‐temporal resolution and fidelity of lung dynamics. Methods An undersampled 3D Fermat looped, orthogonally encoded trajectory (FLORET) was optimized for nonsegmented dynamic acquisitions during forced expiration and a corresponding model‐based ...

Evaluating the Impact of Clonidine and Midazolam Premedication on Emergence Delirium in Pediatric Patients

open access: yesPediatric Anesthesia, EarlyView.
ABSTRACT Background Preoperative anxiety is common in children and is associated with emergence delirium—a distressing postoperative complication characterized by agitation and disorientation. Midazolam has long been the drug of choice for preoperative anxiolysis.

Middle Cerebral Artery Doppler and Cerebroplacental Ratio Predict Adverse Neurological Outcomes in Fetal Growth Restriction

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Objective To assess the efficacy of middle cerebral artery (MCA) Doppler ultrasonography in predicting neurological and respiratory outcomes in fetuses with fetal growth restriction (FGR) and to establish a correlation between MCA Doppler and head circumference (HC). Method Retrospective cohort study examining singleton pregnancies affected by
