CEREBRAL ANGIOGRAPHY

Cerebral Angiography — The Gold Standard

Advanced diagnostic imaging for precise visualization of the brain's blood vessels.

Introduction

Introduction

Cerebral angiography is a minimally invasive diagnostic procedure that uses contrast dye and X-ray imaging to produce detailed pictures of the blood vessels in the brain and neck. It remains the gold standard for evaluating vascular conditions of the brain.

This advanced imaging technique allows neurovascular specialists to visualize the intricate network of arteries and veins, identifying abnormalities with a level of precision that non-invasive imaging cannot match.

Indications

Why Is This Test Ordered?

Your doctor may recommend cerebral angiography to diagnose or evaluate several vascular conditions, including:

Brain aneurysms — detecting, measuring, and assessing rupture risk
Arteriovenous malformations (AVMs) — abnormal connections between arteries and veins
Vessel narrowing (stenosis) — identifying blockages in carotid or intracranial arteries
Stroke cause determination — locating the source of a stroke or TIA
Arterial dissections — tears in artery walls affecting blood flow
Vasculitis — inflammation of blood vessels in the brain
Tumor blood supply mapping — planning for surgical or endovascular treatment of brain tumors
Conditions diagnosed by cerebral angiography
Procedure

What to Expect During the Procedure

1
IV & Sedation
An IV line is placed in your arm for medication and fluids. You will receive moderate sedation to help you relax — you will be comfortable but not fully asleep.
2
Catheter Access
The doctor numbs a small area on your groin or wrist, then inserts a thin catheter into the artery. The catheter is gently guided through your arterial system to the blood vessels in your neck and brain.
3
Contrast Injection & Imaging
Contrast dye is injected through the catheter while X-ray images are taken rapidly from multiple angles. You may feel a warm sensation when the dye is injected, but this is normal and passes quickly.
4
Catheter Removal & Pressure
After all necessary images are obtained, the catheter is removed. Pressure is applied to the access site to prevent bleeding. A compression device or manual pressure is used until the puncture seals.
5
Recovery
You will rest flat in a recovery area for 4–6 hours while the access site is monitored. Most patients go home the same day. You will need someone to drive you home and should avoid strenuous activity for a few days.
