Ultrasound, or sonography, is a reliable and non-invasive medical imaging technique that uses high-frequency sound waves, without radiation. The echoes reflected by the tissues are converted into real-time images, allowing for accurate and painless examination of many organs, vessels, and soft tissues in 2D or 3D.

Ultrasound is often the first-line examination. It can be used to examine the abdominal organs, blood vessels, soft tissues, neck, joints, and breasts. It is also used to guide medical procedures such as biopsies, punctures, and drainages.
We discuss your symptoms and review previous imaging to determine the appropriate ultrasound examination.
You will be placed on an examination bed, and the area to be examined must be exposed. A gel will be applied to the skin to ensure good transmission of sound waves and to obtain optimal image quality.
The probe sends ultrasound waves into the body and captures their return in the form of echoes. A computer converts these echoes into images that are visible on the screen in real time, allowing the organs, vessels, and tissues being examined to be seen instantly.
If necessary, Doppler ultrasound can be used to observe blood flow in vessels and certain organs, helping to detect circulation abnormalities or vascular disorders in real time.
Once the gel has been removed and your clothes put back on, you can resume your normal activities. The images are analyzed by the radiologist, who will send the results to your doctor.
Ultrasound is a radiation-free imaging technique. In addition to examining organs, it can be used to assess infants' hips according to Graf, guide interventional procedures (biopsies, punctures, infiltrations), and perform functional analyses.
No, ultrasound uses sound waves, not radiation, and is safe for everyone, including infants and pregnant women.
No. A standard ultrasound scan is painless. You may feel slight pressure from the probe. When used to guide interventional procedures, a needle may sometimes be needed to inject medication or take a sample.
Most examinations take 10–20 minutes. Complex assessments or Doppler studies may take slightly longer, but preparation and recovery are minimal.
Ultrasound can assess abdominal organs, vessels, thyroid and salivary glands, lymph nodes, breasts, joints, muscles, tendons and soft tissues. It is also used for infant hip screening and for guiding interventions.
Doppler imaging measures the speed and direction of blood flow. It is used to evaluate blood vessels and circulation to organs, and to detect problems such as narrowing or blockages in the vessels.
