Emerging techniques in atherosclerosis imaging

Area of Science:

• Cardiovascular Imaging
• Immunomodulated Diseases
• Vascular Biology

Background:

• Atherosclerosis is a widespread, chronic inflammatory disease impacting numerous vascular beds globally.
• Current imaging primarily assesses morphological features like stenosis, limiting comprehensive risk assessment.
• Advances in CT, MR, and PET imaging enhance speed and resolution, expanding clinical utility.

Purpose of the Study:

• To review current imaging techniques for atherosclerosis.
• To explore how multimodality imaging enhances the depiction of plaque morphology and composition.
• To highlight the potential of novel tracers and contrast agents for assessing plaque metabolic state.

Main Methods:

• Review of modern imaging modalities including CT, MR, and PET.
• Discussion of multimodality imaging approaches.
• Integration of novel biological tracers and "smart" contrast agents.

Main Results:

• Modern scanners offer improved speed and spatial resolution for cardiovascular imaging.
• Multimodality imaging provides insights into vessel wall constituency and metabolic processes.
• Novel agents can target specific disease processes and reveal plaque metabolic state.

Conclusions:

• Advanced imaging modalities significantly improve the depiction of atherosclerotic plaque morphology.
• Multimodality imaging and novel tracers enhance cardiovascular risk prediction by detailing plaque characteristics.
• Future applications hold potential for precise clinical assessment of atherosclerotic disease activity.
