Important Things to Know About Ultrasound
Ultrasound is a safe, radiation-free imaging method that shows a range of body tissues. Ultrasound systems use high-frequency sound waves to create images that help doctors evaluate tissues. Ultrasound can be used to evaluate areas such as blood vessels in the neck, abdomen, and legs as well as monitor fetal development.
During the ultrasound exam, a technologist applies a warm gel and moves a wand-like transducer across the skin. Scan times are typically less than 60 minutes.
