Subarachnoid Haemorrhage in Malta : Are outcomes adversely affected due to lack of a local neurovascular service? [PDF]

, 2014
Objective: This study was performed to assess the incidence, treatment and outcome of non-traumatic Subarachnoid Haemorrhage (SAH) in an island which does not offer a neurovascular service and to determine whether such limitation is associated with a ...

Fetal brain MRI analysis: Towards clinical translation and impact

Developmental Medicine &Child Neurology, EarlyView.
Emerging AI‐based methods demonstrate the feasibility of automating image acquisition, motion correction and 3D reconstruction, segmentation, biometry, and quality control in fetal brain MRI, signaling a shift towards more quantitative assessment, and enabling precise characterization and assessment of the developing brain.

Re‐evaluation of the dinosaur tail sign: Analysis of spinal magnetic resonance imaging signs in patients with chronic post–dural‐puncture headache

Headache: The Journal of Head and Face Pain, EarlyView.
Abstract Objective This study aimed to assess magnetic resonance imaging (MRI) findings of the lumbar spine in patients with chronic post–dural‐puncture headache. Background Post–dural‐puncture headache is a common complication after dural puncture usually resolving within 14 days.

Human cerebral arterial morphogenesis explored by 3D microscopic imaging of cleared embryos: Bridging the gap between embryonic and adult anatomy

Journal of Anatomy, EarlyView.
We provide a description of human embryonic cerebral arterial development based on whole‐mount immunostaining, tissue clearing, three‐dimensional (3D) light‐sheet microscopy imaging, and anatomically informed virtual segmentation of human embryos. Findings are compared with adult radiological anatomy. We provide a detailed account of the development of

Sodium Oxybate Alters Sleep Architecture and Reduces Emotional Selectivity in Memory‐Related Responses

Journal of Sleep Research, EarlyView.
ABSTRACT Sleep supports memory consolidation. Non‐rapid eye movement (NREM) and rapid eye movement (REM) sleep have been proposed to support, respectively, declarative memory consolidation and the integration of the memory affective dimension. Here, we used sodium oxybate (SXB) to modify the NREM/REM proportion during one sleep night and assessed ...

Human In Vivo Validation of Frequency‐Dependent QTI

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2642-2659, December 2026.
ABSTRACT Purpose The aim of this work is to investigate if q‐space trajectory imaging (QTI) waveforms can be designed to probe QTI metrics at a single centroid frequency under realistic experimental conditions for in vivo human brain imaging. Methods Realistic diffusion encoding waveforms based on double‐rotation gradient waveform and magic‐angle ...

Free‐Breathing Hepatic Oxygen Extraction Fraction (OEF) Mapping Using Radial GESSE

Magnetic Resonance in Medicine, Volume 96, Issue 6, Page 2840-2847, December 2026.
ABSTRACT Purpose Noninvasive assessment of hepatic oxygenation is relevant for evaluating liver both in acute and long‐term liver pathologies. However, existing methods are limited to single‐slice acquisitions and require breath‐holding. This study aims to develop and evaluate a motion‐robust technique for whole‐liver oxygen extraction fraction (OEF ...

View Order With Arbitrary Center Echoes

Magnetic Resonance in Medicine, Volume 96, Issue 5, Page 2127-2139, November 2026.
ABSTRACT Purpose To provide explicit, vendor‐independent view‐order constructions that enable selection of an arbitrary center echo in multi‐shot imaging, with a focus on RARE and MPRAGE. Methods Vendor‐independent view‐order methods were developed to assign echo and shot indices to a prescribed set of phase encodes, enabling explicit selection of the ...

World Trade Center neurotoxicant exposure severity is associated with cortical thinning and regional brain atrophy: a neuroimaging study of general responders at midlife

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Exposure to aerosolized pollutants is a risk factor for cognitive impairment and dementia, but the specific features of exposure‐related neurodegeneration remain unclear. METHODS We measured the World Trade Center Neurotoxicant Exposure Severity Index (WTC‐NESI) in 218 responders and unexposed controls aged 44‐65 years.
