The Cerebral Arterial Wall in the Development and Growth of Intracranial Aneurysms

Applied Sciences, 2022
A considerable number of people harbor intracranial aneurysms (IA), which is a focal or segmental disease of the arterial wall. The pathophysiologic mechanisms of IAs formation, growth, and rupture are complex.

Towards Dual-Use Training Simulator in Interventional Neuroradiology

Current Directions in Biomedical Engineering, 2023
Cerebral aneurysms are common lesions in the general population and are increasingly treated by endovascular procedures. Training of these methods not only improves the learning period of physicians but also increases patient safety.

Gadolinium-Enhanced Extracranial MRA Prior to Mechanical Thrombectomy Is Not Associated With an Improved Procedure Speed

Frontiers in Neurology, 2019
Objectives: To assess whether performing a pre-intervention gadolinium-enhanced extracranial magnetic resonance angiogram (MRA) in addition to intracranial vascular imaging is associated with improved thrombectomy time metrics.Methods: Consecutive ...

Machine learning to predict in-stent stenosis after Pipeline embolization device placement

Frontiers in Neurology, 2022
BackgroundThe Pipeline embolization device (PED) is a flow diverter used to treat intracranial aneurysms. In-stent stenosis (ISS) is a common complication of PED placement that can affect long-term outcome.

Low baseline ischemic water uptake is directly related to overestimation of CT perfusion-derived ischemic core volume

Scientific Reports, 2022
Computed-tomography perfusion (CTP) is frequently used to screen acute ischemic stroke (AIS) patients for endovascular treatment (EVT), despite known problems with ischemic “core” overestimation. This potentially leads to the unfair exclusion of patients

Determining body height and weight from thoracic and abdominal CT localizers in pediatric and young adult patients using deep learning

Scientific Reports, 2023
In this retrospective study, we aimed to predict the body height and weight of pediatric patients using CT localizers, which are overview scans performed before the acquisition of the CT.

The Siesta Habit is Associated with a Decreased Risk of Rupture of Intracranial Aneurysms

Frontiers in Neurology, 2017
BackgroundPrevious studies have examined an association between the siesta habit and hypertension, as well as coronary heart disease. However, the relationship between a siesta and the risk of rupture of an intracranial aneurysm (IA) has not yet been ...
