Multi-task Deep Learning for Cerebrovascular Disease Classification and MRI-to-PET Translation [PDF]

arXiv, 2022
Accurate quantification of cerebral blood flow (CBF) is essential for the diagnosis and assessment of cerebrovascular diseases such as Moyamoya, carotid stenosis, aneurysms, and stroke. Positron emission tomography (PET) is currently regarded as the gold standard for the measurement of CBF in the human brain.

Evaluation of using a double helical, closed-cell stent-retriever (Skyflow) for thrombectomy procedures in acute arterial occlusion: A preclinical study and a clinical trial

Journal of Interventional Medicine, 2022
Background and purpose: Stent retriever thrombectomy is the standard therapeutic approach for ischemic stroke with acute large-vessel occlusion. This study evaluated the safety and efficacy of a new thrombectomy device (Skyflow) in the treatment of acute

An automated multiscale ensemble simulation approach for vascular blood flow [PDF]

, 2015
Cerebrovascular diseases such as brain aneurysms are a primary cause of adult disability. The flow dynamics in brain arteries, both during periods of rest and increased activity, are known to be a major factor in the risk of aneurysm formation and rupture. The precise relation is however still an open field of investigation.

Prior Antithrombotic Therapy Is Associated With Cerebral Microbleeds in Ischemic Stroke Patients With Atrial Fibrillation and/or Rheumatic Heart Disease

Frontiers in Neurology, 2019
Background and purpose: Cerebral microbleeds (CMBs) could contribute to an increased risk of intracerebral hemorrhage in patients with antithrombotic therapy (antiplatelets or anticoagulants). Antithrombotic agents are commonly prescribed to the patients

TSI-Net: A Timing Sequence Image Segmentation Network for Intracranial Artery Segmentation in Digital Subtraction Angiography [PDF]

arXiv, 2023
Cerebrovascular disease is one of the major diseases facing the world today. Automatic segmentation of intracranial artery (IA) in digital subtraction angiography (DSA) sequences is an important step in the diagnosis of vascular related diseases and in guiding neurointerventional procedures. While, a single image can only show part of the IA within the

Patients with treated indolent lymphomas immunized with BNT162b2 have reduced anti‐spike neutralizing IgG to SARS‐CoV‐2 variants, but preserved antigen‐specific T cell responses

American Journal of Hematology, Volume 98, Issue 1, Page 131-139, January 2023., 2023
Abstract Patients with indolent lymphoma undertaking recurrent or continuous B cell suppression are at risk of severe COVID‐19. Patients and healthy controls (HC; N = 13) received two doses of BNT162b2: follicular lymphoma (FL; N = 35) who were treatment naïve (TN; N = 11) or received immunochemotherapy (ICT; N = 23) and Waldenström's macroglobulinemia

Preparation of ROS‐Responsive Exosome Coating of Nitinol Material for Making the Neurointerventional Stent

Advanced Materials Interfaces, 2023
Nitinol (NiTi) alloy is an ideal material for preparing neurointerventional stents due to its excellent mechanical properties and biocompatibility. However, NiTi stents without surface‐specific functionalization cause a high rate of stent thrombosis and ...
