Ultrasound involves exposing part of the body to high-frequency sound waves to produce pictures of the inside of the body. Ultrasound exams do not use ionizing radiation. Ultrasound imaging is a painless procedure that helps physicians diagnose and treat medical conditions.
A Doppler ultrasound study may be part of an ultrasound examination. Applications include abdomen and pelvis, OB/GYN, carotid, aorta, thyroid, renal, bladder, scrotum/testicles, veinous ultrasound, arterial ultrasound, and echo.
