20 de may. de 2024 · Slow or stagnant flow in vessels may also be detected as a loss of normal flow void and high signal on T2/FLAIR and T1 C+ (intravascular enhancement), and presence of a the prominent vessel sign on SWI may indicate poor collateralisation 23.
20 de may. de 2024 · It is believed that hemorrhagic transformation occurs as a result of preserved collateral perfusion (from adjacent vessels/territories) or from reperfusion of infarcted tissues which have weakened vessels (i.e. from extravasation or diapedesis) 1.
16 de may. de 2024 · Here we describe the complete protocol that we use to characterize the vasculature of different organs in mice encompassing the methods to fluorescently label vessels, optically clear tissue, collect 3D vascular images, and quantify these vascular images with a semi-automated approach.
17 de may. de 2024 · Interactions between localization of vasospasm in the CoW, vasospasm severity, anatomical variations, and changes in collateral flow directions are investigated to relate localization and vasospasm severity to clinical outcomes like the development of infarct. The Circle of Willis (CoW) is a ring-like network of blood vessels that perfuses the brain. Flow in the collateral pathways that ...
8 de may. de 2024 · Introduction Cerebral small vessel disease (CSVD) is the major cause of vascular cognitive decline and dementia (Jellinger, 2007; Pantoni, 2010 ). It refers to a series of clinical, imaging, and pathological syndromes caused by various etiologies affecting small blood vessels in the brain (Ter Telgte et al., 2018 ). Currently, the diagnosis of CSVD relies mainly on conventional imaging ...
