Insights
Magnetic Resonance Imaging (MRI) offers a non-invasive method to assess vulnerable atherosclerotic plaques. This technique aids in understanding disease mechanisms and monitoring drug efficacy to reduce atherosclerosis-related mortality.
Area of Science:
- Cardiovascular Medicine
- Medical Imaging
- Biomedical Engineering
Background:
- Atherosclerosis is a primary cause of global mortality and morbidity.
- Vulnerable atherothrombotic plaques drive thromboembolic events in major arteries.
- Current management strategies have limitations in reducing long-term adverse outcomes.
Purpose of the Study:
- To highlight the role of Magnetic Resonance Imaging (MRI) in evaluating atherosclerotic plaques.
- To explore MRI's potential in monitoring anti-atherosclerosis therapies.
- To emphasize the importance of understanding plaque biology for novel treatment development.
Main Methods:
- Utilizing MRI for detailed morphological and functional assessment of plaques.
- Non-invasive, non-irradiating, and reproducible imaging approach.
- Application in arterial beds including carotid, coronary, and lower limb arteries.
Main Results:
- MRI provides comprehensive plaque characterization.
- Demonstrates potential for monitoring therapeutic interventions.
- Facilitates deeper understanding of atherosclerosis at cellular and molecular levels.
Conclusions:
- MRI is a promising tool for the comprehensive evaluation of atherosclerosis.
- It can guide the development of novel treatment strategies.
- Ultimately, MRI may help reduce the persistent high mortality and morbidity associated with this disease.
Abstract:
Atherosclerosis remains the leading cause of long term morbidity and mortality worldwide, despite significant advances in its management. Vulnerable atherothrombotic plaques are predominantly responsible for thromboembolic ischaemic events in arterial beds, such as the carotid, coronary and lower limb arteries. MRI has emerged as a non-invasive, non-irradiating and highly reproducible imaging technique which allows detailed morphological and functional assessment of such plaques. It also has the potential to monitor the efficacy of established and evolving anti-atherosclerosis drugs. It is envisaged that by careful identification and understanding of the underlying cellular and molecular mechanisms that govern atherosclerosis, novel treatment strategies can be formulated which may reduce the persistent high mortality and morbidity rates associated with this disease. MRI shows promise in achieving this goal.
