Vascular ultrasound uses Doppler imaging to answer specific artery or vein questions. It can support appropriate DVT, venous reflux and carotid assessment pathways, but it must never delay emergency care for stroke, pulmonary embolism or severe acute symptoms.
Use the examination finder to search the currently listed scan options by symptom, body area or preparation need. The clinic team should confirm the most appropriate examination, preparation and booking pathway before an appointment is made.
An ultrasound scan answers a specific imaging question. It does not replace emergency assessment, urgent maternity care, urgent breast assessment or a wider clinical review where those are needed.

View full profileHow to choose the appropriate examination
The best scan depends on the body area, symptoms, pregnancy status, prior results and the clinical question. If you are unsure, start with a private GP or speak to the clinic team before booking.
| Concern or starting point | Possible route | Important note |
|---|---|---|
| New one-sided leg swelling, pain, warmth or tenderness | Urgent DVT ultrasound pathway | Chest pain, breathlessness, collapse or coughing blood requires 999. |
| Varicose veins, persistent aching or heaviness | Venous reflux ultrasound pathway | New sudden leg symptoms need urgent assessment for DVT instead. |
| A clinically appropriate carotid Doppler question | Carotid Doppler pathway | Sudden facial weakness, speech difficulty or limb weakness requires 999 immediately. |
Preparation and appointment planning
Vascular preparation depends on the scan. Most DVT, venous reflux and carotid Doppler examinations do not require fasting; wear loose clothing that allows access to the relevant leg or neck area and confirm instructions at booking.
Preparation varies by examination. Confirm the current instructions with the clinic when booking, and bring relevant referral letters, previous reports or test results where available.
When to use an urgent pathway instead
Call 999 for sudden stroke symptoms, chest pain, sudden breathlessness, coughing blood, collapse or severe deterioration. New one-sided leg swelling or pain should be assessed promptly and should not wait for a routine appointment if symptoms are worsening.
A routine private scan should never delay emergency or specialist urgent assessment. If you are unsure how urgent a symptom is, use NHS 111 or the appropriate emergency service.
