Ultrasound (also known as a sonogram) produces images by generating high-frequency sound waves. A transducer placed on your skin, with warm gel, sends and receives sound waves into the body which produces gray scale echoes. These echoes produce images of the internal structures shape and size. The process is completely free of radiation or harmful side effects. Exam times range from 30 minutes to 60 minutes based on the organs to be evaluated.
