  • Gait / Stance problems.
  • Loss of speech (Dysphasia and aphasia).
  • Difficult swallowing (Dysphagia).
  • Pre-operative assessment for high risk patients, i.e. heart bypass (CABG).
  • Post intervention follow-up i.e. carotid endarterectomy and stent or bypass.
  • Trauma in the distribution of the carotid arteries.  (Suspected dissection, AV-Fistula, Pseudoaneurysm).
  • Pulsatile neck masses.

What is included with this ultrasound scan?

An electronic ultrasound report of the examination including any measurements same day as your appointment.

What does the scan involve?

During the scan you will be asked to loosen any clothing around the neckline and gel will be placed over your skin. An ultrasound probe will then be placed on your skin and moved along your neck. An image will appear on the monitor which will be translated by a professionally qualified Ultrasonographer. The examination lasts around 15-20 minutes and is pain free. At the end of the examination the Ultrasonographer will give you a verbal report with a formal ultrasound scan report with any recommendations being sent to you which you can take to your regular healthcare professional.
