PET imaging of atherosclerosis

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Molecular Biology

Background:

• Atherosclerosis is a chronic inflammatory arterial disease leading to plaque rupture and ischemic events.
• Assessing cardiovascular risk requires evaluating disease activity, plaque vulnerability, and anatomical features.
• Conventional imaging techniques are limited in assessing active atherosclerotic mechanisms and plaque vulnerability.

Purpose of the Study:

• To explore the potential of molecular imaging, specifically Positron Emission Tomography (PET), for assessing atherosclerosis.
• To investigate vascular PET imaging as a tool for understanding plaque biology and cardiovascular risk.
• To evaluate the role of PET in guiding and monitoring anti-atherosclerosis treatments.

Main Methods:

• Utilizing targeted radiolabeled probes for noninvasive in vivo tracking of active atherosclerotic mechanisms.
• Employing Positron Emission Tomography (PET) for molecular imaging of the arterial wall.
• Analyzing current evidence supporting the clinical application of vascular PET imaging.

Main Results:

• Molecular imaging with PET can visualize active atherosclerotic mechanisms noninvasively.
• Vascular PET imaging provides insights into plaque biology and vulnerability.
• Evidence suggests PET can quantify cardiovascular risk and monitor treatment responses.

Conclusions:

• Molecular imaging with PET is a promising tool for cardiovascular risk assessment.
• PET imaging can help distinguish high-risk atherosclerotic plaques.
• This technique supports personalized anti-atherosclerosis treatment strategies and monitoring.
