In silico modelling to advance arterial spin labelling magnetic resonance imaging
Rationale Arterial spin labelling (ASL) magnetic resonance imaging (MRI) of the lungs is an imaging methodology used for the measurement of pulmonary perfusion. Unlike other pulmonary perfusion imaging techniques such as Positron emission tomography (PET), Single-photon emission computed tomography …

Relationship between lifestyle factors and neurodegeneration in midlife as expressed on arterial spin labelling and structural magnetic resonance imaging
… and neurodegeneration in midlife as expressed on arterial spin labelling and structural magnetic resonance imaging. Methods: A systematic review of the relationship between lifestyle and neurodegeneration in midlife as expressed on functional magnetic resonance imaging (fMRI) was undertaken. …

Blood-Oxygen-Level-Dependent Parameter Identification using Multimodal Neuroimaging and Particle Filters
… and Cerebral Blood Flow (CBF) (from Arterial Spin Labelling (ASL)) in addition to the BOLD signal and the fusion of this information is achieved in a Particle Filter (PF) framework. The trace plots and the correlation coefficients of the parameter estimates from the PF reflect …

ARTERIAL STIFFNESS AND CEREBRAL BLOOD FLOW AMONG OLDER ADULTS
… found a relationship for the vascular factors arterial stiffness and cerebral blood flow (CBF) with mild cognitive impairment (MCI). This study analyzes arterial stiffness and CBF as potential pre-clinical factors of AD in the Alzheimer’s Disease Prevention Participant Repository (ADPPR) …

Investigating white matter alterations and secondary neurodegeneration with MRI imaging and pathology in a mouse model of ischaemic stroke
… Cerebral blood flow (CBF) was measured using arterial spin labelling (ASL) MRI in the white and grey matter regions. Diffusion tensor imaging (DTI) assessed white matter integrity via fractional anisotropy (FA) and mean diffusivity (MD). Immunohistochemistry evaluated astrocyte (GFAP) and …

Intracranial Vascular Findings in a Tri-Ethnic Population – MR Phenotypes and Physiological Parameters
… morphologic heterogeneity of the intracranial arterial network and the impact of its vari- able structure on intracranial haemodynamics, cerebral blood flow, and the pathogenesis of cerebrovascular disease is still lacking, while the continuous adoption and increasing avail- ability of …

Understanding the role of cerebrovascular health in cognitive aging: a multi-modal noninvasive human neuroimaging approach
… in a group of older adults (ages 55-85). Using arterial spin labeling (ASL) to quantify CBF, we found that blood flow in the gray matter was positively correlated with CRF and negatively correlated with age (Zimmerman et al., 2014). Subsequent analyses revealed that CRF fully mediated the …

Arterial Spin-labelled MRI Analyses to Advance Adolescent Bipolar Disorder Research and Clinical Applications
Cerebral blood flow (CBF) is foundational to brain function in health and disease. Through three distinct analyses, the aim of this thesis is to extend current understanding of CBF in adolescent bipolar disorder and to enable future understanding of CBF in other brain diseases. CBF measurement can …

Physiological responses of human retina and choroid to retinal image defocus: Implications for myopia
… same time of day in two visits. A non-invasive arterial spin labelling MRI (ASL-MRI) technique was optimised to image chorio-retinal blood perfusion in both eyes by magnetically labelling the blood. Experiment (3): In a clinical trial, thirty healthy young adults (age: 25 ± 4 years, SER: +2.00 …
