Duplex Ultrasound Scan
What is a duplex ultrasound scan?
A duplex (Doppler) ultrasound scan is a non-invasive, painless test that combines a standard ultrasound scan with a Doppler assessment to create a colour map of your vessels and surrounding anatomy. Duplex ultrasound may be used to assess the shape and patency of both veins and arteries throughout the body, and is a vital investigation for any vascular surgeon.
What happens during a duplex ultrasound scan?
If you are undergoing an arterial duplex ultrasound scan this will take place with you lying on a couch; for venous duplex ultrasound scans the individual performing the scan may also require you to stand. Once you are positioned comfortably a special jelly is applied to the region being scanned and a probe attached to the ultrasound machine is placed onto your skin. The probe emits ultrasonic sound waves which bounce off structures in your body according to tissue density. These "echoes" are detected by the probe and used to produce a detailed ‘live’ image of the inside of your body, which is seen on the monitor.
How long does an ultrasound scan take?
The scan takes between 20 and 90 minutes but does depend on the area being scanned. A scan of the arteries in both legs and abdomen may take up to an hour and half to perform.
Are there any risks associated with ultrasound scans?
Ultrasound scans do not involve radiation and are painless and safe. You will be able to return to work and drive immediately after the scan has been completed.
What happens after an ultrasound scan?
The scans are individually reported by our radiology team and reviewed with each client’s lead surgeon. You will then be reviewed in clinic to discuss the scan findings and how we may be able to help.
