European Journal of Neurology, Volume 30, Issue 2, Page 380-388, February 2023., 2023 Abstract Background and purpose An early understanding of stroke mechanism may improve treatment and outcome in patients presenting with large vessel occlusion stroke (LVOS) treated with mechanical thrombectomy (MT). We aimed to investigate whether spontaneous external carotid artery (ECA) embolism detection during MT is associated with stroke etiology

Small intracranial aneurysms of the anterior circulation: A negligible risk?
European Journal of Neurology, Volume 30, Issue 2, Page 389-398, February 2023., 2023 Abstract Background and purpose According to the International Study of Unruptured Intracranial Aneurysms, small (<7 mm) unruptured intracranial aneurysms (IAs) of the anterior circulation (aC) carry a neglectable 5‐year rupture risk. In contrast, some studies report frequencies of >20% of all ruptured IAs being small IAs of the aC.

Hemorragia subaracnoideia e angiografia cerebral por Tomografia Computorizada.
Acta Médica Portuguesa, 2001 We present a review of 57 cases of nontraumatic subarachnoid hemorrhagesubmitted to CT angiography of the cerebral vessels. The purpose of our study was to estimate the value of CT angiography in the detection of intracranial aneurysms.

Physics-informed neural networks for improving cerebral hemodynamics predictions [PDF]
arXiv, 2021 Determining brain hemodynamics plays a critical role in the diagnosis and treatment of various cerebrovascular diseases. In this work, we put forth a physics-informed deep learning framework that augments sparse clinical measurements with fast computational fluid dynamics (CFD) simulations to generate physically consistent and high spatiotemporal ...

Advanced Science, EarlyView.The breakdown of the blood‐brain barrier (BBB) after cerebral ischemia can cause brain injury and induce potentially fatal consequences. Currently, there exist few dependable and low‐cost imaging techniques for visualizing the BBB. This investigation effectively engineered an albumin‐specific covalently tagged near‐infrared‐II (NIR‐II) dye, serving as ...
