Noninvasive imaging modalities to visualize atherosclerotic plaques

Area of Science:

• Cardiovascular Medicine
• Medical Imaging
• Diagnostic Technologies

Background:

• Atherosclerotic cardiovascular disease (ASCVD) is a leading global cause of mortality, exacerbated by rising rates of diabetes and obesity.
• Early detection of high-risk atherosclerotic plaques is essential for preventing ASCVD events.
• Noninvasive imaging technologies have advanced significantly, enabling in vivo visualization of plaques.

Purpose of the Study:

• To review the current noninvasive imaging modalities for detecting atherosclerotic plaques.
• To discuss the role of these imaging techniques in cardiovascular risk assessment.
• To summarize the advantages and disadvantages of computed tomography (CT), magnetic resonance imaging (MRI), and positron emission tomography (PET).

Main Methods:

• Review of current literature on noninvasive imaging for atherosclerotic plaques.
• Discussion of computed tomography (CT) applications and limitations.
• Discussion of magnetic resonance imaging (MRI) applications and limitations.
• Discussion of positron emission tomography (PET) applications and limitations.

Main Results:

• Noninvasive imaging refines cardiovascular risk assessment.
• Imaging aids in selecting optimal therapeutic strategies.
• Efficacy of medical therapies can be evaluated using these modalities.
• Each modality (CT, MRI, PET) has distinct advantages and disadvantages for plaque visualization.

Conclusions:

• Noninvasive imaging plays a vital role in the prevention and management of atherosclerotic cardiovascular disease.
• Advanced imaging techniques improve risk stratification and treatment personalization.
• Understanding the strengths and weaknesses of CT, MRI, and PET is crucial for clinical application.
