Doppler ultrasound (or Doppler ultrasound): definition, procedure, price

This medical imaging technique allowing the speed of blood circulation in certain vessels of the body to be observed is indicated in several cases and does not present a risk to health.

Doppler ultrasound is a non-invasive medical examination which combines classic ultrasound and the Doppler effect in order to study both the anatomy of the vessels and the circulation du sang.

As explained on the Orléans University Hospital website (source 1), it is based on the use of ultrasound : high frequency sound waves, imperceptible to the human ear. These waves, emitted by a probe, pass through the tissues and are reflected to produce images in real time. The addition of doppler allow to analyze the speed and direction of blood circulation in the vessels, which provides essential information on their proper functioning.

These three terms are often confused, but they correspond to complementary techniques:

Doppler ultrasound is prescribed in many situations, particularly for explore the arteries and the veins :

It is also used for guide certain medical procedures (such as vein treatments) or monitor cardiovascular diseases.

There are two main categories of examination:

Very common, this examination allows to explore the veins and arteries of the legs. It is particularly prescribed for:

It can be performed lying down, then completed in a standing position to better analyze the functioning of the veins.

This examination concerns vessels of the arm, forearm and hand. In particular, it allows:

The examination of neck arteries is essential for preventing stroke (AVC). It allows you to identify:

It is often recommended in the presence of cardiovascular risk factors (hypertension, diabetes, smoking, high cholesterol).

This exam is used to explore the aorta and abdominal arteries. In particular, it allows:

Doppler ultrasound can also be used to examine the heart. It allows you to visualize:

This examination is essential for diagnose or monitor heart disease (heart failure, valvular heart disease, malformations, etc.).

The exam generally takes place in a lying position. The doctor applies a probe on the skin, after having deposited a gel which facilitates the transmission of ultrasound. It then moves the probe along the vessels to be explored. During the exam it is possible to hear sounds features a pulsating noise for the arteries and a more continuous noise for the veins.

These sounds correspond to blood flow analyzed in real time.

In the majority of cases, no preparation is necessary. Alone exception : abdominal Doppler ultrasound. You may be asked to follow a low-residue diet in the preceding days to limit intestinal gas, which can interfere with visualization.

The examination is carried out in a specialized office (angiologuephlebologist), at the hospital or in a medical imaging center.

No, the Doppler ultrasound is painless. However, discomfort may be felt if the area examined is sensitive (for example in the case of phlebitis), or if the practitioner must exert greater pressure with the probe.

The exam lasts on average 30 minutesbut may be longer depending on the area studied or the pathology sought.

There does not exist no contraindication to Doppler ultrasound. As the University Hospitals point out, this examination is safe because it does not use X-rays. It can therefore be carried out on all patients, including pregnant women.

The results are generally given immediately orally by the doctor. A written report, often accompanied by images, is then given to the patient or sent to the prescribing doctor.

The cost varies depending on the type of exam and location, generally between €70 and €150. When prescribed by a doctor, it is reimbursed at 70% by Health Insurance, the rest can be covered by mutual insurance.
