3D ultrasound could spot hidden clot risks in aneurysms
NCT ID NCT05841524
First seen Jul 21, 2026 · Last updated Jul 22, 2026 · Updated 1 time
Summary
This study explores whether a special 3D ultrasound technique, called vector flow imaging, can predict where blood clots form inside abdominal aortic aneurysms. Researchers will scan 14 people with small aneurysms (under 5.5 cm), half with existing clots and half without. They will also test whether injecting contrast microbubbles improves the image quality. The goal is to see if this non-invasive method can reliably measure blood flow patterns linked to clot formation.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
- What this could lead to
- If successful, this imaging technique could help predict which aneurysms are at risk of forming dangerous blood clots, guiding earlier treatment.
- What could go wrong
- This is a very small feasibility study with only 14 participants, so results may not apply broadly. The technique is still experimental and not ready for routine use.
