Transradial Neurointerventional Approach to Basilar Tip Aneurysm: Case Report and Technical Note

Iranian Journal of Neurosurgery, 2017
Cerebral angiography through transfemoral approach is preferred in most of the situation though in cardiovascular surgery transradial angiography is accounted as the superior standard.

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, EarlyView.
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 ...

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.

Reflections on the Utility of the Retina as a Biomarker for Alzheimer's Disease: A Literature Review. [PDF]

, 2019
As a part of the central nervous system, the retina may reflect both physiologic processes and abnormalities related to diseases of the brain. Indeed, a concerted effort has been put forth to understand how Alzheimer's disease (AD) pathology may manifest

Failure rate of the pulmonary embolism rule‐out criteria rule for adults 35 years or younger: Findings from the RIETE Registry

Academic Emergency Medicine, EarlyView.
Abstract Background The use of a computed tomography pulmonary angiogram to diagnose pulmonary embolism (PE) has increased, leading not only to higher PE diagnoses but also to overdiagnosis and unnecessary radiation exposure, even in young patients despite a lower PE incidence.

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 ...

Validation of the Sudbury Vertigo Risk Score to risk stratify for a serious cause of vertigo

Academic Emergency Medicine, EarlyView.
Abstract Introduction In 2022, nearly 0.5 million Canadians visited an emergency department (ED) for dizziness, accounting for over 3.5% of all ED visits. Of these patients, only 2%–5% received a serious diagnosis. The cost of ED and inpatient care for dizziness in Canada exceeds $200 million per year, of which neuroimaging accounts for a large ...
