What are some common uses of the procedure?

Ultrasound: Gallbladder

Ultrasound: Kidney

Ultrasound: Liver

Ultrasound examinations can help to diagnose a variety of conditions and to assess organ damage following illness.

Ultrasound is used to help physicians diagnose symptoms such as:

• pain
• swelling
• infection

Ultrasound is a useful way of examining many of the body's internal organs, including but not limited to the:

• heart and blood vessels, including the abdominal aorta and its major branches
• liver
• gallbladder
• spleen
• pancreas
• kidneys
• bladder
• uterus, ovaries, and unborn child (fetus) in pregnant patients
• eyes
• thyroid and parathyroid glands
• scrotum (testicles)

Ultrasound is also used to:

• guide procedures such as needle biopsies, in which needles are used to extract sample cells from an abnormal area for laboratory testing.
• image the breasts and to guide biopsy of breast cancer (see the Ultrasound-Guided Breast Biopsy page).
• diagnose a variety of heart conditions and to assess damage after a heart attack or other illness.

Doppler ultrasound images can help the physician to see and evaluate:

• blockages to blood flow (such as clots)
• narrowing of vessels (which may be caused by plaque)
• tumors and congenital malformation

With knowledge about the speed and volume of blood flow gained from a Doppler ultrasound image, the physician can often determine whether a patient is a good candidate for a procedure like angioplasty.
