Before Your Appointment

The abdominal aorta lies deep in the abdomen, and bowel gas is the main obstacle to a clear image. You do not need to fast completely, but avoiding gas-producing foods for 24 hours before your scan significantly improves image quality.

Avoid Gas-Producing Foods For 24 hours before your scan, avoid beans, lentils, cabbage, fizzy drinks, and chewing gum. These produce bowel gas that can obscure the aorta on ultrasound-scan.

Loose, comfortable clothing that exposes the abdomen easily
A two-piece outfit (top and trousers/skirt) is ideal
Avoid tight waistbands or belts that are difficult to loosen

Insurance authorisation code (if applicable)
Any previous scan reports or GP letters
A list of current medications (especially antihypertensives)
Arrive 5 minutes early to complete a brief patient history form

Greyscale (B-mode) imaging of the abdominal aorta
Aortic diameter measurement (transverse and longitudinal)
Iliac artery assessment (common and external iliac)

Aortic Aneurysm (AAA) Ultrasound Scan

Ultrasound is regularly being used to evaluate abdominal aortic aneurysms. Abdominal aneurysm is a swelling of the aorta, the main blood vessel that brings blood for your heart to the rest of the body. The aorta is around 2.5 in the abdominal area, it can, however, swell to more than 5 cm.
Aneurysms are more common in men of 65+ years of age than in women and younger men, and they can be fatal as large aneurysms can burst. According to NHS Choices 8 out of 10 people with aortic aneurysm or AAA die.

It is highly unlikely that small aneurysms will cause any symptoms but large aneurysm can cause the following symptoms:

Intense back or abdominal pain
Rapid pulse
Nausea and vomiting
Excessive sweating
Shock
Although the causes of AAA are not fully understood, risk factors include obesity, high blood pressure, smoking and high cholesterol

Your Journey

From confirmation to report — here is exactly what to expect at every stage of your AAA ultrasound-scan appointment.

You will receive an email confirmation immediately after booking, including your appointment time, address, and preparation instructions. A reminder is sent 24 hours before your appointment.

The clinic is at 29 Weymouth Street, Marylebone, London W1G 8GR — a 5-minute walk from Regent's Park and Great Portland Street tube stations. Arrive 5 minutes early to complete a brief patient history form.

Your HCPC-registered sonographer will review your history, discuss your symptoms or risk factors, and confirm the scan protocol. You will be asked to lie on the examination couch and expose your abdomen.

Warm gel is applied to your abdomen. The sonographer uses a linear or curvilinear probe to image the aorta from the diaphragm to the bifurcation, measuring diameter in both transverse and longitudinal planes. Colour Doppler confirms flow patterns and identifies any mural thrombus or calcification.

Your sonographer will give you verbal feedback before you leave. Your written report — with aortic measurements, NICE NG156 classification (normal / small / medium / large), and clinical recommendations — is sent to you within 24 hours. If urgent findings are identified, you will be advised immediately.

Frequently Asked Questions

Do I need a GP referral to book an AAA ultrasound-scan?

No GP referral is required. You can book directly online at any time. If you have a referral letter or previous scan results, bring them along — they provide useful clinical context for your sonographer.

What exactly should I avoid eating before the scan?

Avoid beans, lentils, peas, cabbage, broccoli, cauliflower, fizzy drinks, and chewing gum for 24 hours before your appointment. These produce bowel gas that can obscure the aorta. You can eat and drink normally otherwise — a light meal is fine. There is no requirement to fast completely.

How will I receive my report?

Your written report will be emailed to you within 24 hours of your appointment. It includes aortic diameter measurements, NICE NG156 size classification, Doppler flow findings, and clinical recommendations. A copy can also be sent directly to your GP or specialist if you provide their details.

Can I cancel or reschedule my appointment?

Yes. You can cancel or reschedule up to 24 hours before your appointment at no charge. Cancellations made within 24 hours of the appointment time may incur a cancellation fee. Please call 020 3633 4902 or email the clinic to make changes.

Does my private health insurance cover this scan?

Many private health insurance policies cover vascular ultrasound-scans. Contact your insurer before booking to confirm coverage and obtain an authorisation code. Bring this code to your appointment. The clinic can provide an itemised receipt for reimbursement claims.

What happens if the scan finds an aneurysm?

If an aneurysm is detected, your sonographer will explain the findings verbally and your written report will include a NICE NG156 classification. Small aneurysms (3.0–4.4 cm) are monitored with repeat scans. Medium aneurysms (4.5–5.4 cm) require closer surveillance. Large aneurysms (5.5 cm or more) require urgent vascular surgical review — your sonographer will advise you to seek this immediately.
