What is a Doppler Ultrasound Scan?

This is an ultrasound scan sometimes referred to as a duplex or Doppler. This scan uses ultrasound to produce images of the blood vessels throughout the body. It is a safe and effective way to assess blood flow in arteries and veins. This test is painless and does not use any radiation or needles. There are no risks associated.  

How is the scan performed?

There is no preparation needed and you may eat and drink as usual prior to the investigation

A clinical scientist (who may be male or female) will perform and interpret your ultrasound scan. You may be asked to remove an item of clothing during the scan however dignity will be maintained throughout. The scan will be performed with you led down or seated on the scanning couch. Ultrasound gel will be applied and the ultrasound probe will moved along the area being scanned. Some pressure may be applied. The clinical scientist will comment on the findings and write a report for the requesting doctor.

Types of vascular assessment:

  • Abdominal Aortic Aneurysm (AAA) surveillance
  • Ankle Brachial Pressure Index (ABPI)
  • Carotid arteries for suspected Transient Ischaemic Attack (TIA) or stroke
  • Endovascular Aneurysm Repair (EVAR) surveillance post AAA repair
  • Fistula scans, fistula flow studies and vascular access
  • Graft surveillance post vascular surgery
  • Renal artery ultrasound
  • Toe Brachial Index (TBI)
  • Upper and lower limb veins for Deep Vein thrombosis (DVT)
  • Upper and Lower limb arteries for peripheral vascular disease (PAD)
  • Upper limb arteries and veins for Thoracic Outlet syndrome (TOS)
  • Varicose veins scans and pre surgery marking of veins
