Summary
Magnetic resonance imaging (MRI) effectively diagnosed aortic aneurysms in 13 patients, accurately showing extent, location, and mural thrombus. MRI also improved evaluation of thoracic aneurysms compared to other methods.
Area of Science:
- Cardiovascular Imaging
- Diagnostic Radiology
Background:
- Aortic aneurysms pose significant diagnostic challenges.
- Accurate imaging is crucial for treatment planning and patient outcomes.
Purpose of the Study:
- To evaluate the diagnostic utility of 0.35 tesla magnetic resonance imaging (MRI) for aortic aneurysms.
- To compare MRI findings with angiography, computed tomography (CT), and intraoperative data.
Main Methods:
- Thirteen patients with aortic aneurysms (abdominal, thoracic, thoraco-abdominal) underwent MRI.
- Imaging utilized transversal, coronal, and sagittal planes with ECG gating for thoracic cases.
- MRI results were correlated with angiography, CT, and surgical findings.
Main Results:
- MRI accurately depicted aneurysm extent and location in all 13 patients.
- MRI superiorly identified mural thrombus compared to angiography (10/10 vs. 6/10).
- MRI provided better visualization of brachiocephalic artery relationships in thoracic aneurysms than angiography and CT.
- MRI successfully demonstrated all three aortic dissections.
Conclusions:
- 0.35 tesla MRI shows promise as a valuable tool in diagnosing aortic aneurysms.
- MRI offers advantages in characterizing aneurysm extent, mural thrombus, and thoracic involvement.
- Further research is warranted to establish MRI's definitive role in aortic aneurysm management.
