Technicians use ultrasound images to non-invasively evaluate the veins of the lower extremities, detecting venous reflux and blood clots in the legs. Venous reflux is the underlying cause of spider veins and varicose veins.

 

Preparation

 

• Drink at least four (4) cups of water the morning of the ultrasound.

• Do NOT wear compression stockings 24 hours prior to the scheduled test. Wearing the compression stockings within 24 hours prior may invalidate the test results causing the test to be rescheduled.

• The test takes approximately forty-five (45) minutes. Be prepared to undress from the hip down.
