Vein Ultrasound
in Los Angeles


Vein Ultrasound imaging, or sonography, is a procedure that produces images of the inside of the body using high-frequency sound waves. These images are captured in real-time and are able to show the structure and movement of blood flow.


What is Vein Ultrasound used for?

Vein Ultrasound imaging can be used to monitor and diagnose a wide range of conditions. In particular, it is effective at evaluating the location and severity of venous insufficiency. It can also detect deep vein thrombosis and is an important tool during varicose vein procedures.

At the Los Angeles Vein Center, we offer in-office Ultrasound imaging to help with diagnosis and procedure. This leads to fast and effective treatment of various venous disorders. Dr. Lee has been credentialed by the American Registry for Diagnostic Medical Sonography (ARDMS) and is a Registered Physician in Vascular Interpretation (RPVI). In addition, our ultrasounds are performed by a Registered Vascular Technologist (RVT) credentialed by ARDMS and a Registered Vascular Specialist credentialed by Cardiovascular Credentialing International (CCI).


Who is a candidate for vein ultrasound?

If you’re showing signs or symptoms of decreased blood flow in the arteries or veins of your legs, arms, or neck, your doctor could order a vein ultrasound. A reduced amount of blood flow may be due to a blockage in the artery, a blood clot inside a blood vessel, or an injury to a blood vessel. Vein ultrasound can estimate the blood flow through your blood vessels.

These are conditions that could merit your doctor requesting a vein ultrasound:

  • Deep vein thrombosis — This is a condition that occurs when a blood clot forms in a vein deep inside your body (usually in the legs or hips)
  • Superficial thrombophlebitis — This is an inflammation of the veins due to a blood clot in a vein just below the skin’s surface.
  • Arteriosclerosis — This is a narrowing or hardening of the arteries that supply blood to the legs and feet.
  • Thromboangiitis obliterans — This is a rare disease where the blood vessels of the hands and feet become inflamed and swollen.
  • Vascular tumors in your arms or legs

What are the benefits of a vein ultrasound?

A vein ultrasound is a noninvasive, simple procedure that can be used to diagnose many different conditions by producing images of the soft tissues, which often do not show up well on x-rays. There is no ionizing radiation used during this procedure and is a proven safe diagnostic tool.

What are the risks involved with vein ultrasound?

Ultrasound waves have no harmful effects on humans. There are no risks inherent in these tests. At times the clot may not be able to be identified, especially if the clot is below the knee in the calf. But this really isn’t a risk pertaining to the test itself.


What happens during a vein ultrasound? ultrasound machine used for varicose veins

During the ultrasound, the patient is positioned on an examination table and a clear gel is applied to the area being examined. A transducer is then firmly pressed against the skin and swept back and forth to record the sound waves that are used to obtain the image. The image appears on a computer screen in real-time, so that the patient and doctor can view it together.


How long does a vein ultrasound take?

Ultrasound tests usually take between 30 and 45 minutes.

Is a vein ultrasound painful?

There is little if any discomfort during a vein ultrasound. The transducer is pressed against your skin and moved along your arm or leg. The procedure is simple.


Can vein ultrasound tests show blood clots?

Yes. Finding clots is one of the main purposes of these imaging tests. Clots occur in a deep vein in the legs or the hip area. Duplex ultrasound processes are used. In the first part, brightness modulation ultrasound (also known as B-mode ultrasound) is used to obtain an image or picture. Once the area with the potential clot is defined, the sonographer (the operator of the ultrasound machine) tries to collapse or compress the veins. If a vein cannot be compressed because it has a clot, then the diagnosis of deep vein thrombosis is made.

The second phase of duplex ultrasound is used to detect abnormalities of blood flow. Sound waves are bounced off the blood within a vein. Flowing blood changes the sound waves by the Doppler effect. The ultrasound machine can detect these changes and determine whether the blood inside a vein is flowing normally. If there is an absence of blood flow, the diagnosis of deep vein thrombosis is confirmed.
