An ultrasound is an examination using high-frequency sound waves to create images. During an ultrasound, a small device called a transducer is used in contact with the skin with a small amount of gel. The transducer emits high-frequency sound wave, which bounce off internal tissues and organs, creating echoes. These echoes are converted into real-time images that are viewed on screen and interpreted by a sonographer. Afterwards the radiologist will review the images to provide a report to your referring doctor.
Ultrasound is a safe procedure and does not involve radiation.
While ultrasound is a valuable tool, it has its limitations as sound waves don’t travel well through air or bone. As a result it isn’t effective at imaging body parts that have gas in them or are hidden by bone.
