The Human Biomarker Navigator integrates the disease continuum, biomarker dynamics, cross‐organ biomarker networks, biomarker classification, and technology‐driven paradigms. It maps how biomarkers link multi‐system physiology and pathology across the nervous, respiratory, endocrine, circulatory, immune, digestive, urinary, reproductive, and ...

ABSTRACT Background Gadolinium‐based contrast agents are used in brain MRI to improve the visualization of disorders and improve the delineation of lesions. Higher doses of GBCAs can improve lesion sensitivity but may have safety implications, particularly in light of recent findings on gadolinium retention and deposition.

Research progress of cerebral blood flow measured by arterial spin labeling in Alzheimer's disease
Cerebral blood flow (CBF) changes are closely related to Alzheimer's disease (AD). Arterial spin labeling (ASL) uses water proton in blood as an endogenous contrast agent to obtain CBF, which has attracted must attention in AD studies due to its ...

Autosomal dominant Alzheimer's disease (ADAD) is a small subset of Alzheimer's disease that is genetically determined with 100% penetrance. It provides a valuable window into studying the course of pathologic processes that leads to dementia.

Arterial spin labelling magnetic resonance imaging of the brain: techniques and development [PDF]
This thesis centres on the development of arterial spin labelling (ASL) MRI, a non-invasive technique to image cerebral perfusion. In the first chapter I explain the principles of cerebral blood flow (CBF) quantification using ASL beginning with the ...

ABSTRACT Background Whether signal intensity (SI) on Silent MRA reflects hemodynamics in brain arteriovenous malformations (BAVMs) is unclear. Objectives To evaluate the relationship between Silent MRA SI and 4D flow‐derived hemodynamic parameters and examine whether Silent MRA‐based metrics are associated with symptomatic hemorrhage in BAVM.

Voxel-Wise Perfusion Assessment in Cerebral White Matter with PCASL at 3T; Is It Possible and How Long Does It Take? [PDF]
To establish whether reliable voxel-wise assessment of perfusion in cerebral white matter (WM) is possible using arterial spin labeling (ASL) at 3T in a cohort of healthy subjects.Pseudo-continuous ASL (PCASL) with background suppression (BS) optimized ...
