Summary
Computed tomography (CT) is the primary imaging method for suspected aortic aneurysms, offering high accuracy. Additional imaging like digital subtraction angiography (DSA) or magnetic resonance imaging (MRI) is rarely needed.
Area of Science:
- Radiology
- Vascular Imaging
- Medical Diagnostics
Background:
- Aortic aneurysms require accurate imaging for diagnosis and treatment planning.
- Evaluating the utility of different imaging modalities is crucial for optimal patient care.
Purpose of the Study:
- To analyze the utilization and indications of computed tomography (CT), digital subtraction angiography (DSA), and magnetic resonance imaging (MRI) in patients with suspected aortic aneurysms.
Main Methods:
- Retrospective analysis of 383 patients examined with CT (SCT/MSCT) over 18 months.
- Review of 17 patients who underwent DSA and 15 patients who underwent MRI.
- Examination of indications for DSA (endoluminal therapy planning, unclear CT findings, aortic dissection) and MRI (prior CT, contrast intolerance).
Main Results:
- CT was the predominant imaging modality, performed in 383 patients.
- DSA was used for specific indications like endoluminal therapy planning or clarifying CT results.
- MRI was utilized in select cases, often following CT or due to contrast agent intolerance.
Conclusions:
- Computed tomography (CT) is a well-established and generally sufficient imaging modality for suspected aortic aneurysms.
- CT offers good image quality, high diagnostic accuracy, and wide availability.
- Additional DSA or MRI examinations are required in less than 5% of cases, highlighting CT's primary role.
