Ultrasound is a noninvasive and safe medical imaging method that uses high-frequency sound waves to create images of the inside of the body. The sound waves bounce off organs and tissues, they return as echoes, which are then turned into images displayed on a monitor.

Ultrasound allows doctors to assess blood flow and examine blood vessels in real time without the need for invasive procedures. The technique, called vascular ultrasound or Doppler ultrasound, uses sound waves to create images of veins and arteries, helping to detect a variety of conditions related to blood circulation.

Preparing for your ultrasound is simple. It’s best to wear loose, comfortable clothing for easy access to the area being examined. Avoid eating or drinking a few hours before the exam, if indicated, for ultrasounds in your abdomen. Arrive early to complete any forms. Expect to have a clear gel applied to the area being examined.
