Your Magnetic Resonance Angiography

We want to ensure that you receive the highest level of healthcare. This means keeping you educated and informed about what is involved in the different stages of your Magnetic Resonance Angiography. If you have any questions or concerns, please speak with your specialist or medical team.

Understanding Magnetic Resonance Angiography

Magnetic Resonance Angiography (MRA) is a type of Magnetic Resonance Imaging (MRI) Scan that uses strong magnetic fields and radio waves to create detailed images of your blood vessels. It helps doctors identify narrowing, blockages, aneurysms, or other abnormalities without the need for invasive surgery.

It is often used to:

• Examine arteries in the brain, neck, chest, abdomen, and legs
• Detect aneurysms or vascular malformations
• Evaluate narrowing or blockages caused by
  atherosclerosis
• Assess blood flow after surgery or stent placement.

Why It Is Done

An MRA provides clear, detailed images of your blood vessels without exposure to ionising radiation. In some cases, contrast dye (gadolinium) is used to enhance the images.

Common reasons include:

• Investigating stroke or transient ischaemic attack (TIA)
• Assessing suspected aneurysm or vascular malformation
• Detecting narrowing or blockages in arteries
• Monitoring known vascular disease.

Preparing for Your Procedure

What to Tell Your Doctor

Let your care team know if you:

• Have a pacemaker, metal implants, or surgical clips
• Have had previous allergic reactions to MRI contrast dye
• Have kidney problems (as contrast dye may not be suitable)
• Are pregnant or may be pregnant
• Experience claustrophobia or anxiety in enclosed spaces.

Pre-Procedural Instructions

Your team will give you detailed instructions, which may include:

Packing for the Hospital

Bring the following on the day of your procedure:

• A list of current medications and allergies
• Photo ID
• Comfortable clothing without metal zips or fasteners
• Any required hospital paperwork.

Leave valuables at home.

The Day of Your Procedure

On Arrival

• Check in at the admissions desk.
• A staff member will confirm your details and review your safety questionnaire.

Before the Procedure

• You will change into a hospital gown if required.
• An intravenous (IV) line will be placed if contrast dye is needed.
• The radiographer will explain the process and answer any last questions.

What to Expect During the Procedure

Step-by-Step Overview

STEP 1: Positioning

• You will lie on a motorised table that slides into the MRI scanner

STEP 2: Scanning

• The scanner uses magnetic fields and radio waves to take images.
• Loud tapping or knocking sounds will be heard; you will be given earplugs or headphones.
• You will need to remain very still. At times, you may be asked to hold your breath for a few seconds.

STEP 3: Contrast Injection (if needed)

A contrast dye will be injected through your IV line to enhance blood vessel images.

STEP 4: Completion

• The Scan typically takes 30–60 minutes.
• Once complete, the IV line is removed, and you may get dressed.

Recovery After the Procedure

In the Hospital

• You can usually go home immediately after the Scan.
• If contrast dye was used, you may be asked to drink plenty of fluids to help flush it out.
• If you received sedation, you will need someone to accompany you home.

Caring for Yourself at Home

Resume normal activities unless told
otherwise.

When to Seek Medical Attention

Contact your care team or go to the Emergency Room if you experience:

• Severe allergic reaction (rash, swelling, difficulty breathing) after contrast injection
• Persistent pain or swelling at the IV site
• Dizziness, chest pain, or unusual symptoms following the Scan.

Follow-Up Appointments

• Your doctor will review the Scan results and discuss them with you.
• Follow-up may include further imaging, specialist referral, or treatment.
• Results are typically available within 1–2 weeks.
