Ultrasound

Ultrasound uses high-frequency sound waves and a computer to create images of blood vessels, tissues and organs. Ultrasound is used to view internal organs as they function, and to evaluate blood flow through various vessels.

Ultrasound today aids in the diagnosis of many conditions, commonly those involving the kidneys, bladder and uterus, the heart (called echocardiography) and the spleen, liver, gallbladder, uterus, ovaries, thyroid and testicles.

Doppler ultrasound is used to look at blood flow and can determine if there are any problems within the veins and arteries. Vascular ultrasound is used to see the vascular system (the network of veins and arteries inside the body), including detection of blood clots.
