Iterative Navigator‐Based Retrospective Motion Correction for Multi‐Shot Brain MR Elastography and Evaluation of Single‐Shot Post‐Reconstruction Correction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Brain MR elastography (MRE) is uniquely sensitive to subject motion, as even small phase deviations can produce large errors in the mechanical properties estimated. Existing motion correction strategies have not been validated for MRE and are often incompatible with complex multi‐shot or joint temporal reconstructions.

Toward Brain Biosignature at 7 T—Repeatability of a Multiparametric CEST, QSM, QTI, and Sodium Imaging Protocol

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose To evaluate the repeatability of an extended multiparametric 7 T MRI protocol for voxel‐wise tissue characterization combining morphological, CEST, QSM, QTI, and Sodium contrasts. Methods A repeatability study was performed in 12 volunteers without diagnosed neurological disease on a 7 T MRI system, using a comprehensive acquisition ...

Fast Multiparametric ASL MRI via Multi‐Dimensional Acceleration and Subspace Reconstruction

open access: yesMagnetic Resonance in Medicine, EarlyView.
ABSTRACT Purpose Multi‐post‐labeling delays (PLDs) multi‐echo times (TEs) arterial spin labeling (ASL) MRI enables simultaneous quantification of cerebral blood flow (CBF), arterial transit time (ATT), and blood–brain barrier (BBB) water exchange, but requires long scan times due to the combination of multi‐TEs, PLDs, and repeated control–label ...

Broadening the Movement Disorder Spectrum in MECP2‐Related Disorders: From Ataxia to Opsoclonus‐Myoclonus

open access: yesNeurology and Clinical Neuroscience, EarlyView.
ABSTRACT Background MECP2‐related disorders encompass a broad spectrum of movement disorders, but opsoclonus has not been characterized within this spectrum. Case Presentation We describe a girl with a de novo pathogenic MECP2 variant who developed an acute/subacute cerebellar presentation following a prolonged febrile illness, evolving from prominent ...

Chronic high‐altitude exposure and intracerebral hemorrhage: A novel perspective from the vascular‐immune‐neuronal network

open access: yesNeuroprotection, EarlyView.
Long‐term chronic high‐altitude hypobaric hypoxia increases susceptibility to ICH, particularly among migrant populations lacking EPAS1/SENP1 adaptive genetic variants relative to high‐altitude indigenous residents. Persistent hypoxia initiates blood–brain barrier (BBB) breakdown, aberrant glial and immune activation, and progressive neuronal injury ...

Heterozygous Beta‐Thalassaemia in Pregnancy: Two Rare Causes of Severe Fetal Anemia Requiring Intrauterine Blood Transfusions

open access: yesPrenatal Diagnosis, EarlyView.
ABSTRACT Aim In this article, we present two cases of severe fetal hemolytic anemia based on a beta‐thalassaemia trait inherited from a single parent. Results These cases, presented at 20 and 28 weeks' gestation, necessitated intra‐uterine blood transfusions.
