An ultrasound uses high-frequency sound waves to take images of the heart, digestive, reproductive or urinary tracts, or other soft tissue structures within the body. An ultrasound is also used to gather vital information and measurements of your unborn baby.

An ultrasound is a common, non-invasive, painless procedure used to investigate a wide variety of conditions. A hand-held device called a transducer is used to perform the ultrasound. The transducer slides slowly across your skin delivering images to the ultrasound monitor.

Abdominal Ultrasound can include imaging of the liver, gallbladder, pancreas, kidneys and aorta. You must not eat, drink or smoke from midnight the night before the exam, until the exam is complete.

Pelvic Ultrasound can include the examination of the uterus, overies, and bladder. You will be required to drink 32 ounces of water before your exam.

Vascular Ultrasound can include the examination of carotid, venous, arterial Doppler and echocardiogram. No special preparation is needed.

Thyroid, breast and testicle ultrasounds do not require special preparation.

Obstetrical or prenatal ultrasounds are used to gather important data on your growing baby. You may be able to see your baby's arms, legs, and head. You will be required to drink 16 to 32 ounces of water before this exam.
