Summary
Positron Emission Tomography (PET) accurately measures human brain blood flow and metabolism. This review details how PET studies advance understanding of stroke and cerebrovascular disease pathophysiology.
Area of Science:
- Neuroscience
- Medical Imaging
- Cerebrovascular Medicine
Background:
- Understanding the link between cerebral circulation and brain cell function is crucial for stroke pathophysiology and treatment.
- Cerebral blood flow and metabolism are key indicators of brain health.
- Cerebrovascular diseases pose significant health challenges.
Purpose of the Study:
- To review normal human cerebral blood flow and metabolism.
- To discuss human Positron Emission Tomography (PET) studies in various cerebrovascular diseases.
- To elucidate how PET imaging enhances the understanding of cerebrovascular disease pathophysiology.
Main Methods:
- Utilizing Positron Emission Tomography (PET) for quantitative in vivo regional measurements.
- Reviewing existing human PET studies on cerebrovascular conditions.
- Analyzing data on cerebral blood flow and cellular metabolism.
Main Results:
- PET is the sole technique for accurate, quantitative in vivo regional measurements of cerebral circulation and metabolism.
- PET studies provide insights into the pathophysiology of ischemic stroke, carotid artery disease, vascular dementia, intracerebral hemorrhage, and aneurysmal subarachnoid hemorrhage.
- These studies have significantly contributed to understanding human cerebrovascular disease.
Conclusions:
- PET imaging is indispensable for studying human cerebrovascular diseases.
- PET-derived data on cerebral blood flow and metabolism are vital for advancing neurological research.
- Continued PET research promises improved diagnostics and treatments for cerebrovascular conditions.
