Summary
Assessing aortic atherosclerosis with Magnetic Resonance Imaging (MRI) and Transesophageal Echocardiography (TEE) is crucial for predicting cardiovascular events. Both MRI and TEE show strong agreement in evaluating thoracic aortic plaques.
Area of Science:
- Cardiovascular Imaging
- Atherosclerosis Research
Background:
- Aortic atherosclerosis is linked to major cardiovascular events.
- Accurate assessment of plaque degree and extent is diagnostically valuable.
Purpose of the Study:
- To evaluate the diagnostic value of MRI and TEE in assessing thoracic aortic atherosclerosis.
- To compare the agreement between MRI and TEE in characterizing atherosclerotic plaques.
Main Methods:
- Utilized Magnetic Resonance Imaging (MRI) including T1, proton density, and T2-weighted sequences.
- Employed Transesophageal Echocardiography (TEE) as a primary tool for thoracic aortic atheroma study.
- Applied American Heart Association criteria for grading advanced atherosclerotic lesions.
Main Results:
- MRI and TEE can identify elementary plaque components.
- Advanced atherosclerotic lesions were graded using established criteria.
- A close agreement was observed between MRI and TEE assessments of thoracic aortic atherosclerosis.
Conclusions:
- Both MRI and TEE are effective in assessing thoracic aortic atherosclerosis.
- The findings support the use of both modalities for comprehensive cardiovascular risk evaluation.
