Doppler Ultrasound Scans in London | Arterial & Venous Doppler

Doppler ultrasound is a fast, non-invasive way to assess blood flow in your arteries and veins. It detects blockages, narrowing, clots, aneurysms, and circulation issues early — helping prevent serious complications.

What Is a Doppler Ultrasound?

Doppler ultrasound uses sound waves to measure blood flow direction and speed, unlike traditional ultrasound that only shows structure. Benefits include:

• Painless and safe
• No radiation exposure
• Same-day diagnosis possible
• Suitable for arteries and veins

Arterial vs Venous Doppler

Choosing the right Doppler scan depends on your symptoms and risk factors.

Arterial Doppler

Used when blood flow from the heart to the body may be reduced. Detects narrowed arteries, plaque, and circulation problems.

Symptoms to consider:

• Leg pain when walking (claudication)
• Cold or pale feet/toes
• Dizziness or visual disturbance
• High blood pressure related to kidneys

Venous Doppler

Used when blood flow back to the heart may be impaired. Detects blood clots, valve failure, venous reflux, and swelling.

Symptoms to consider:

• Leg swelling or tenderness
• Visible varicose veins
• Sudden shortness of breath (suspected DVT)

Which Doppler Scan Should I Book?

Here’s a condition-first guide to help you choose the correct Doppler scan:

Arterial Doppler

Ideal for: leg pain, cold/numb limbs, known peripheral arterial disease (PAD). Checks blood flow in limb arteries.

Carotid Doppler

Ideal for: dizziness, TIA/stroke history, family history of stroke. Checks carotid arteries for stroke risk.

Temporal Arteries Doppler

Ideal for: severe headaches, scalp tenderness, jaw pain. Checks temporal arteries for inflammation.

DVT (Deep Vein Thrombosis) Doppler

Urgent booking for: sudden leg swelling, calf pain, recent surgery or travel. Detects dangerous blood clots in deep veins.

Abdominal Aortic Aneurysm (AAA) Scan

Ideal for: family history of aneurysm, pulsating abdomen, male >65, smokers. Checks abdominal aorta size and safety.

Varicose Vein Doppler

Ideal for: visible varicose veins, heavy aching legs, end-of-day swelling. Checks venous reflux and valve function.

Renal Artery Stenosis Doppler (RAS)

Ideal for: difficult-to-control high blood pressure, declining kidney function. Detects narrowing of kidney arteries.

Ankle Brachial Pressure Index (ABPI)

Ideal for: suspected PAD, non-healing leg ulcers, diabetes. Checks blood pressure differences between arms and ankles.

Peripheral Arterial Doppler

Ideal for: leg pain while walking, reduced mobility, known arterial disease. Assesses leg arteries for blockage or narrowing.

Vascular Package for Leg Pain

Ideal for unclear leg pain with swelling or discomfort. Combines arterial and venous assessment for full diagnosis.
