Arm vs groin access for brain blood vessel imaging
Part of Brain & nervous system, Heart & circulation clinical trials.
This trial compares two ways doctors can look at the blood vessels in your brain: through a small tube in your arm or through a small tube in your groin. Both are common, and the study aims to see which is safer and works better.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You are older than 18.
- You need a full picture of the blood vessels in your brain.
- Your arm artery (in the wrist) is wide enough, at least 1.5 mm.
- You are mostly independent in daily life (score of 0–2 on a standard disability scale).
- You do not have conditions that make the procedure risky, like poor blood flow in your hand or a blocked blood vessel in your arm or chest.
- You are able to sign a consent form and attend follow-up visits.

This trial tests a new AI method to create clearer 3D brain images using lower radiation doses during procedures like angiography. It aims to reduce radiation exposure while keeping image quality high for safer diagnosis and treatment.
This trial tests if a robot can help perform a brain artery scan through the wrist as safely and effectively as the standard manual method. It might be an option if you need a detailed look at blood vessels in your brain.
This trial tests a new imaging system and tiny catheter that lets doctors see inside brain blood vessels more clearly during a planned angiogram. It may help people who need follow-up imaging after previous treatment or a diagnostic look at their vessels.
This trial uses your medical images (like MRI or angiography) to create a personalized map of your brain's blood vessels. The goal is to help doctors better plan minimally invasive treatments for aneurysms or arteriovenous malformations.
This trial compares doing a clot-removal procedure through the arm artery versus the leg artery for an emergency stroke caused by a blocked basilar artery. It aims to see which access route is safer and more effective for restoring blood flow when time is critical.
This trial compares two ways to get a second access site during a TAVI procedure: using the wrist artery (radial) or the groin artery (femoral). The goal is to see which approach is safer and works better for patients like you.
