Diagnostic Cerebral Angiography

Diagnostic Cerebral Angiography Experts

We perform over 1,000 angiographic procedures every year at Stony Brook Medicine. Our high experience level allows us to perform these procedures safely and efficiently. 

What is Cerebral Angiography?

Cerebral angiography is a minimally invasive medical test that uses x-rays and a catheter through which an iodine-containing contrast material is inserted into an artery to produce a picture of blood vessels in the brain. 
It's used to examine blood vessels in the brain for abnormalities such as:

• Aneurysm
• Arteriosclerosis
• Arteriovenous malformation (tangled blood vessels)
• Brain tumor
• Blood clot
• Vascular dissection (tear in the artery wall)
• Stroke

Cerebral Angiography at Stony Brook

We perform nearly all of our diagnostic angiography procedures using a transradial approach (through the wrist artery).

This is a safer and easier approach than traditional transfemoral approach (through the leg artery), which is still used at many institutions. Our transradial approach has been supported by extensive data demonstrating lower risks of bleeding, shorter length of hospital stays, shorter periods of bed rest, and greater patient comfort and satisfaction.
