Brain aneurysm study aims to predict rupture risk without surgery

NCT ID NCT04578808

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This study follows 1,000 people with small, unruptured brain aneurysms (3-7 mm) for three years. Researchers will use MRI scans to see if a specific imaging sign—wall enhancement—can predict which aneurysms grow. The goal is to create a safer, personalized monitoring plan so that only high-risk aneurysms get treated.

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 could lead to a personalized follow-up plan for people with unruptured brain aneurysms, reducing unnecessary treatments and anxiety.
What could go wrong
This is an observational study, not a treatment trial. It may not find a reliable predictor, and results may not apply to all aneurysm types or sizes.
