Preparing for your Doppler scan

Painless, no needles and about 15 minutes. Here is how to get the most from it.

A Doppler scan uses ultrasound to show blood flowing through your veins and arteries, live on screen. It is painless, uses no radiation and needs no injection.

For leg scans, wear loose clothing or shorts so the legs are easy to reach. There is no need to fast. For scans of the abdominal aorta, we may ask you not to eat for a few hours beforehand, and the clinic will tell you when you book.

Bring any previous scans, reports and your list of medicines. The doctor explains the images as the scan happens, so you leave knowing what was found and what the next step is.
