8 Απρ 2024 · Specifically, neuroimaging can provide a range of directly or indirectly derived visual representation as well as quantitative analysis of the anatomy, blood flow, blood volume, electrical activity, metabolism, oxygen consumption, receptor sites and many other physiological functions within the CNS.
30 Δεκ 2016 · Imaging enables researchers to identify brain vascular abnormalities, understand disease pathways, evaluate blood-brain barrier (BBB) integrity, recognize and diagnose pathologies and determine efficacy of different therapies and treatments.
MR perfusion imaging refers to several recently developed techniques used to non-invasively measure cerebral perfusion via assessment of various hemodynamic measurements such as cerebral blood volume, cerebral blood flow, and mean transit time.
22 Αυγ 2023 · MRI can be used to measure blood flow, either through the use of injected contrast agents or through magnetically labelling blood, a technique known as arterial spin labelling (ASL).
9 Αυγ 2019 · Molecular brain imaging techniques such as positron emission tomography (PET) provide functional, neurochemical, and neuropathological information at a molecular level, thereby playing a complementary role to anatomical and electrophysiological methods of brain mapping.
16 Σεπ 2020 · While numerous in vivo imaging techniques exist to investigate cerebral haemodynamics in humans, phase-contrast magnetic resonance imaging (MRI) has emerged as a reliable, non-invasive method of quantifying blood flow within intracranial vessels.
18 Οκτ 2016 · Arterial spin labeling (ASL) is a magnetic resonance (MR) imaging technique used to assess cerebral blood flow noninvasively by magnetically labeling inflowing blood.
