Can sound waves replace CT scans for aortic aneurysm monitoring?
NCT ID NCT07752654
First seen Aug 07, 2026 · Last updated Aug 07, 2026
Summary
This study explores whether ultrasound can reliably measure aneurysms in the descending thoracic aorta, the part of the main artery that runs through the chest. Researchers will compare ultrasound measurements with standard CT scans in about 60 adults, including some with known aneurysms and some without. The goal is to see if ultrasound can accurately and consistently measure aneurysm size, which could offer a simpler, radiation-free way to monitor these conditions in the future.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- Active substance
- Ultrasound imaging (transthoracic ultrasound)
- What this could lead to
- If ultrasound proves accurate and reliable, it could offer a non-invasive, radiation-free way to monitor descending aortic aneurysms, potentially reducing the need for repeated CT scans.
- What could go wrong
- This is a small observational study, and ultrasound may not always clearly visualize the aorta due to body shape or other factors. The results will need confirmation in larger studies.
