What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now This study
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.

Summary

This study uses MRI scans to look at plaque buildup in leg arteries of people with peripheral arterial disease. Researchers want to see which plaques are hard to cross with a guidewire and which devices cause the least damage to the vessel wall. The study includes patients undergoing artery procedures and those having leg amputations. It aims to improve how doctors plan and perform these treatments.

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 help doctors choose better devices and techniques for treating blocked leg arteries, potentially reducing complications.
What could go wrong
This is an observational study, not a treatment trial. It may not lead to direct patient benefits, and results may not apply to all patients.

This is an AI summary of the original study and may miss details. Read our disclaimer.
