When is this exam indicated?
Doppler ultrasound is a non-invasive method to diagnose and monitor the main vascular disorders: aneurysms, atherosclerotic lesions, venous insufficiency, thrombosis.
How is it performed?
The examination is generally performed in a supine position with the head extended in order to expose the greatest possible stretch of skin covering the artery to the examiner's evaluation. A probe, which performs the dual function of producing ultrasound and collecting the echoes generated by the underlying tissues, is placed on the skin; the use of gel prevents air from getting between the skin and the probe, reducing the chances of an inaccurate diagnosis.
There are no contraindications for the execution of this examination.
