On the Origin of the Brain Semi‐Heavy Water Deuterium MR Signal Following Administration of Deuterated Metabolic Substrate: A Cautionary Tale

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the extent to which the appearance of HOD in the brain following systemic administration of a deuterated substrate is due to local brain metabolism versus body metabolism. Methods [6,6‐2H2]glucose, which is transported across the blood‐brain barrier (BBB), and [6,6‐2H2]fructose (Fruc), which does not cross the BBB, were ...

Preclinical 1H MRS Study of a Porcine Model Shows Evidence and Mechanisms for Acute Neuronal Injury in Neonatal Cardiopulmonary Bypass (CPB) Surgery

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Congenital heart disease affects 1% of US births, with some infants requiring cardiothoracic surgery under cardiopulmonary bypass (CPB). Optimal surgical parameters to minimize neuronal injury are unknown. We used serial 1H MRS in a neonatal CPB porcine model to assess acute neuronal damage and associated injury mechanisms.

Simultaneous Assessment of Intracranial Artery and Paravascular CSF Pulsation Using 3D Whole‐Brain Diffusion‐Prepared Cine bSSFP (DECAF) MRI

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To propose a noninvasive and quantitative MRI approach to simultaneously assessing intracranial artery pulsation and paravascular cerebrospinal fluid (CSF) pulsation in the human brain. Methods We developed a 3D whole‐brain Diffusion‐prepared Cine bSSFP (DECAF) MRI technique, with improved motion‐sensitized driven‐equilibrium providing

DynaTOF: Time‐Resolved Noncontrast Cerebral MR Angiography Using Spatially Modulated RF Saturation

Magnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To develop a time‐resolved extension of three‐dimensional time‐of‐flight MR angiography, termed Dynamic TOF (DynaTOF), that exploits intrinsic RF saturation behavior to enable noncontrast visualization of cerebrovascular hemodynamics.

Defining the Timing of Radiological Follow‐Up for Detection of Cholesteatoma Recidivism: A Meta‐analysis

Otolaryngology–Head and Neck Surgery, EarlyView.
Abstract Objective Non‐echo‐planar diffusion‐weighted imaging (non‐EPI DWI) magnetic resonance imaging (MRI) has revolutionized postoperative cholesteatoma follow‐up, shifting from surgical to radiological evaluation. Yet, the timing for postoperative imaging remains contentious.
