Ultrasound is a non-invasive imaging scan that uses sound waves to “see” inside your body. At the Metropolitan Vascular Institute, we have an expert team of physicians, nurses, and technologists who are highly trained in ultrasound imaging.

Venous Duplex Ultrasound Scan
The purpose of a venous duplex ultrasound scan is to evaluate venous blood flow in the patient’s arms and/or legs. Patients may experience symptoms such as pain, swelling or varicose veins in the arms or legs. These scans can aid in the diagnosis of venous abnormalities such as a suspected blood clot in a deep vein of the leg (DVT); narrowing or closure (occlusion) of a vein; or impaired blood flow (venous insufficiency).
A Venous Doppler ultrasound study may be part of a venous duplex ultrasound examination. Doppler ultrasound is a special ultrasound technique that allows the physician to see and evaluate blood flow through arteries and veins in the abdomen, arms, legs, neck, or within various body organs such as the liver or kidneys.
Renal Duplex Ultrasound Scan
The renal arteries provide blood flow to the kidneys. Renal artery disease, including narrowing (stenosis) due to atherosclerosis, can result in reduced blood-flow to the kidney. This can cause hypertension (high blood pressure). Renal artery stenosis is the most common correctable cause of hypertension. Long-standing, untreated renal artery disease is also a common cause of kidney failure.
Renal artery disease cannot be diagnosed without specific tests. Renal artery duplex scanning is accurate, non-invasive and cost-effective. Unlike angiography or CT scanning, no injection of X-ray contrast material is required, avoiding the risk of kidney damage from the contrast.
Blood-flow velocities and flow patterns in the aorta and renal arteries are evaluated with Doppler ultrasound. Imaging of the kidneys can provide information about secondary damage to the kidneys from chronic poor blood-flow.
Carotid Duplex Ultrasound Scan
A carotid duplex scan is a test that combines two types of ultrasound to look for blockages in your carotid arteries. Your carotid arteries are located along both sides of your neck. Blocked carotid arteries are a major risk factor for stroke.
Other names for a carotid duplex scan are:
- Carotid Artery Duplex
- Carotid Ultrasound
- Vascular Ultrasound
- Carotid Artery Doppler
