Insights
This review explores human cerebrovascular structure and function, highlighting how magnetic resonance imaging (MRI) can assess brain blood flow and cerebrovascular health. It examines the link between the cardiac pulse and cerebrovascular disease.
Area of Science:
- Neuroscience
- Cardiovascular Science
- Medical Imaging
Background:
- The human cerebrovasculature precisely regulates cerebral blood flow to meet brain metabolic demands.
- It also protects the brain from systemic blood pressure fluctuations, both acutely and chronically.
- Understanding cerebrovascular function is crucial for addressing neurological diseases and neurodegeneration.
Purpose of the Study:
- To review cerebrovascular structure and function.
- To discuss the role of cerebrovascular health in disease and neurodegeneration.
- To explore the application of Magnetic Resonance Imaging (MRI) in studying cerebrovascular physiology.
Main Methods:
- Review of existing literature on cerebrovascular structure and function.
- Description of various MRI techniques for measuring cerebrovascular physiology.
- Analysis of MRI applications in assessing cerebrovascular health.
Main Results:
- Cerebrovascular structure and function are key to brain health.
- MRI offers valuable methods for probing cerebrovascular physiology.
- The cardiovascular system's pulse wave is linked to cerebrovascular disease.
Conclusions:
- Cerebrovascular regulation is vital for brain function and protection.
- MRI is a powerful tool for investigating cerebrovascular health and disease.
- Further research is needed to fill knowledge gaps regarding the cardiovascular system's impact on cerebrovascular disease.
Abstract:
Human cerebrovasculature is finely tuned to enable local changes in blood flow to meet the brain's demands, whilst protecting the brain from systemic changes in blood pressure, both acutely during a heartbeat and chronically over time. This review summarises cerebrovascular structure and function, their role in disease and neurodegeneration and the part MRI measurements can play in probing them. MRI methods to measure various aspects of cerebrovascular physiology are described and placed in context of applications studying cerebrovascular health. The role of the cardiovascular system linking the cardiac pulse wave to cerebrovascular disease and gaps in mechanistic knowledge are highlighted.

Definition and Purpose
An X-ray, or radiograph, is a non-invasive method that uses ionizing radiation to take images of internal structures. It is mainly used in cardiac imaging to examine the heart, lungs, and major blood vessels, aiming to identify abnormalities in the heart's size, shape, and position, such as heart failure, congenital defects, and vascular...
