Comparative Effectiveness of Immersive Virtual Reality and Traditional Didactic Training on Radiation Safety in Medical Professionals: A Crossover Study

Journal of Medical Radiation Sciences, EarlyView.
This study evaluates the comparative effectiveness of immersive virtual reality (VR) training and traditional didactic training on radiation safety among medical professionals, with a focus on reducing radiation exposure. A 2‐year randomised crossover trial involving 39 participants from cardiac catheterisation labs and orthopaedic theatres was ...

LncRNA PVT1 Facilitates Phenotypic Switching of Vascular Smooth Muscle Cells in Intracranial Aneurysms by Recruiting KDM1A to Reduce H3K9me2 Modification

The Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT This study explores the differential expression of lncRNA PVT1 in intracranial aneurysms (IAs) and its role in the phenotypic switching of vascular smooth muscle cells (VSMCs). PVT1 and ALOX5 expressions in the serum of IA patients and healthy controls were detected by qRT‐PCR.

Optic Disc Pallor in Parkinson's Disease: A UK Biobank Study

Movement Disorders, EarlyView.
Abstract Background Recent studies have suggested that retinal changes measured with optical coherence tomography are detectable in early Parkinson's disease (PD), highlighting the potential of ophthalmic biomarkers for diagnosis and monitoring. Objective We set out to investigate the relationship between optic disc pallor measured in fundoscopy images

Segmentation‐assisted vessel centerline extraction from cerebral CT Angiography

Medical Physics, EarlyView.
Abstract Background The accurate automated extraction of brain vessel centerlines from Computed tomographic angiography (CTA) images plays an important role in diagnosing and treating cerebrovascular diseases such as stroke. Despite its significance, this task is complicated by the complex cerebrovascular structure and heterogeneous imaging quality ...

Simultaneous whole‐brain and cervical spine imaging at 7 T using a neurovascular head and neck coil with 8‐channel transceiver array and 56‐channel receiver array

Magnetic Resonance in Medicine, Volume 94, Issue 1, Page 386-400, July 2025.
Abstract Purpose To develop a 7T neurovascular head and neck (NVHN) coil with an extended longitudinal coverage of the brain and cervical spine, with eight transceiver (TxRx) channels and 56 receive (Rx) channels for dynamic parallel‐transmit (pTx) applications. Methods A dual‐row transceiver array with six elements in the upper row and two elements in

Variational data assimilation for transient blood flow simulations [PDF]

arXiv, 2016
Several cardiovascular diseases are caused from localised abnormal blood flow such as in the case of stenosis or aneurysms. Prevailing theories propose that the development is caused by abnormal wall-shear stress in focused areas. Computational fluid mechanics have arisen as a promising tool for a more precise and quantitative analysis, in particular ...

Whole‐brain BOLD responses to graded hypoxic challenges at 7 T, 9.4 T, and 15.2 T: Implications for ultrahigh‐field functional and dynamic susceptibility contrast MRI

Magnetic Resonance in Medicine, Volume 94, Issue 1, Page 262-277, July 2025.
Abstract Purpose Blood oxygen–level dependent (BOLD) functional MRI signals depend on changes in deoxyhemoglobin content, which is associated with baseline cerebral blood volume (CBV) and blood oxygen saturation change. To accurately interpret activation‐induced BOLD responses and quantify perfusion values by BOLD dynamic susceptibility contrast (BOLD ...

An efficient pipeline to compute patient-specific cerebral aneurysm wall tension [PDF]

arXiv
Cerebral aneurysm rupture, leading to subarachnoid hemorrhage with a high mortality rate, disproportionately affects younger populations, resulting in a significant loss of productive life years. A significant proportion of these deaths is due to aneurysmal re-bleeding within the first three days following the initial bleed, prior to treatment.

Pregnancy and Delivery Outcomes in Vascular Ehlers–Danlos Syndrome: A Retrospective Multicentre Cohort Study

BJOG: An International Journal of Obstetrics &Gynaecology, EarlyView.
ABSTRACT Objective We aim to increase knowledge on pregnancy and delivery risks in vascular Ehlers–Danlos Syndrome (vEDS). Our outcomes can contribute to establishing future guidelines for pregnancy and delivery management in women with vEDS. Design Retrospective multicentre cohort study.
