MRI of atherosclerosis

Area of Science:

• Cardiovascular Imaging
• Medical Diagnostics
• Biomedical Engineering

Background:

• Atherosclerosis is a significant cardiovascular disease characterized by plaque buildup in artery walls.
• Current diagnostic methods often focus on lumen stenosis, potentially missing critical plaque information.
• High-resolution, rapid Magnetic Resonance Imaging (MRI) offers a noninvasive window into arterial wall microstructure.

Purpose of the Study:

• To review the current state-of-the-art of MRI for imaging atherosclerosis.
• To explore MRI's potential in assessing atherosclerotic plaque burden and composition.
• To evaluate MRI's capability in identifying vulnerable plaques and guiding clinical decisions.

Main Methods:

• Review of recent advancements in high-resolution, rapid MRI techniques applicable to vascular imaging.
• Analysis of studies investigating MRI for characterizing atherosclerotic lesions in key arterial segments.
• Focus on MRI applications for carotid arteries, aorta, and coronary arteries.

Main Results:

• MRI can noninvasively visualize the fine internal structure of atherosclerotic artery walls.
• Emerging MRI techniques show promise in determining plaque burden and composition.
• Potential exists for MRI to identify vulnerable plaques, aiding in predicting clinical events.

Conclusions:

• MRI is a powerful tool for noninvasive assessment of atherosclerosis.
• Its ability to characterize plaque provides valuable information beyond lumen diameter.
• Further research and validation are ongoing to integrate MRI into clinical practice for treatment decisions.
