Vascular / Doppler Ultrasound
A vascular (or Doppler) ultrasound is a non-invasive scan that checks blood flow in your arteries and veins. It helps detect narrowing, blockages, blood clots, or varicose veins, and assesses circulation in areas like the neck, arms, legs, or abdomen.​
​
A DVT ultrasound is a safe, non-invasive test used to check for blood clots in the deep veins, most commonly in the legs. It helps diagnose deep vein thrombosis, which can cause leg pain or swelling and may lead to serious complications like a pulmonary embolism if not treated.
​​
Carotid Doppler ultrasound is a safe, non-invasive test that uses sound waves to examine the carotid arteries in your neck and check blood flow. It checks the carotid arteries for plaque buildup (atherosclerosis). The carotid arteries carry blood to the brain. It helps detect narrowing or blockages which can increase the risk of stroke.
