IntrA: 3D Intracranial Aneurysm Dataset for Deep Learning [PDF]

arXiv, 2020
Medicine is an important application area for deep learning models. Research in this field is a combination of medical expertise and data science knowledge. In this paper, instead of 2D medical images, we introduce an open-access 3D intracranial aneurysm dataset, IntrA, that makes the application of points-based and mesh-based classification and ...

CT Utilisation in Emergency Department (ED) Assessment of Patients With Suspected Polytrauma: Impact of a Dedicated Trauma Surgical Team

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Introduction We aimed to assess the impact of introduction of a dedicated trauma surgical unit (TSU) on CT utilisation for polytrauma in the Emergency Department (ED). Methods Single centre retrospective cohort study comparing adult patients undergoing CT for polytrauma following TSU introduction (Intervention group, n = 617) to a historical ...

Machine learning algorithms to predict the risk of rupture of intracranial aneurysms: a systematic review [PDF]

Purpose: Subarachnoid haemorrhage is a potentially fatal consequence of intracranial aneurysm rupture, however, it is difficult to predict if aneurysms will rupture. Prophylactic treatment of an intracranial aneurysm also involves risk, hence identifying rupture-prone aneurysms is of substantial clinical importance.

Intracranial hemodynamics simulations: An efficient and accurate immersed boundary scheme [PDF]

arXiv, 2020
Computational fluid dynamics (CFD) studies have been increasingly used for blood flow simulations in intracranial aneurysms (ICAs). However, despite the continuous progress of body-fitted CFD solvers, generating a high quality mesh is still the bottleneck of the CFD simulation, and strongly affects the accuracy of the numerical solution.

The FRED‐X Flow Diverter—An Australian Experience

Journal of Medical Imaging and Radiation Oncology, EarlyView.
ABSTRACT Background The FRED X flow diverter features antithrombotic surface treatment to reduce thrombogenicity. This study evaluated the safety and efficacy of FRED X in treating intracranial aneurysms in the Australian setting. Methods Clinical, procedural and imaging data were retrospectively reviewed for a consecutive series of patients at a ...

Non-Kolmogorov Turbulence and Inverse Energy Cascade in Intracranial Aneurysm: Near-Wall Scales Suggest Mechanobiological Relevance [PDF]

arXiv, 2020
The genesis, growth and rupture of intracranial aneurysm (IA) are open questions in neurovascular medicine until the present moment. The complexity of aneurysm mechanobiology and pathobiology staggeringly combine intertwining biological and physical processes that are tightly connected.

Transitional flow in intracranial aneurysms - a space and time refinement study below the Kolmogorov scales using Lattice Boltzmann Method [PDF]

arXiv, 2015
Most Computational Fluid Dynamics (CFD) studies of hemodynamics in intracranial aneurysms are based on the assumption of laminar flow due to a relatively low (below 500) parent artery Reynolds number. A few studies have recently demonstrated the occurrence of transitional flow in aneurysms, but these studies employed special finite element schemes ...

Intra-operative Optimal Flow Diverter Selection for Intracranial aneurysm treatment [PDF]

Proc. SPIE 12468, Medical Imaging 2023: Biomedical Applications in Molecular, Structural, and Functional Imaging, 124680P (10 April 2023)
During intracranial aneurysm (IA) treatment with Diverters (FDs), the device/parent artery diameters ratio may influence the ability of the device to induce aneurysm healing response. Oversized FDs are safer to deploy but may not induce enough hemodynamic resistance to ensure aneurysm occlusion. Methods based on Computational Fluid Dynamics (CFD) could

Toward molecular phenotyping of temporal lobe epilepsy by spatial omics

Epilepsia, EarlyView.
Abstract Objective In temporal lobe epilepsy (TLE), detection of the epileptogenic zone predicts a good surgical outcome. When submitted to 18F‐fluorodeoxyglucose positron emission tomography (PET), some patients display lateralized, focal hypometabolism in the temporal lobe (PET+), whereas others appear normometabolic (PET−).

Long‐term risk and characteristics of cerebrovascular events after upper body radiotherapy among childhood cancer survivors in the DCCSS‐LATER cohort

International Journal of Cancer, Volume 156, Issue 10, Page 1858-1872, 15 May 2025.
What's new? Due to the nature of cancer treatments, childhood cancer survivors have an increased risk of serious adverse events later in life. Here, the authors examined the incidence of cerebrovascular events (CVEs) among childhood cancer survivors who had received upper body radiotherapy.
