Ultrasound uses high frequency sound waves to create images by detecting sound waves reflected from internal organs and structures. The reflected sound waves are sent to a computer for processing and image construction. Ultrasound does not use ionizing radiation (x-ray).

Ultrasound is painless and safe. It can be safely used to image and assess the growing fetus. Ultrasound has many other applications and is used to evaluate organs and structure such as: blood vessels, gallbladder, abdominal organs, testicles, and thyroid. It is also used to provide guidance of needle placement for biopsy, venous and arterial access. The most common procedures are described below.

Carotid Doppler

This procedure uses directional high frequency sound waves to visualize the arteries in the neck and measure the speed and direction of blood flow through those blood vessels. It is a safe and painless procedure usually performed to determine areas of narrowing, reversed or turbulent flow.

Venous Doppler

A Venous Doppler uses directional high frequency sound waves to see the larger veins in the leg and arm. It is a safe and painless procedure usually performed to evaluate blood clot or insufficient function of valves.

Abdominal Ultrasound

An Abdominal Ultrasound uses directional high frequency sound waves to see organs and vessels within the abdomen. Some of the organs seen are the liver, gallbladder, kidney, pancreas and aorta. It is a safe and painless procedure.

Pelvic Ultrasound

A Pelvic Ultrasound uses directional high frequency sound waves to see organs and vessels within the pelvic region. Organs seen are the uterus, ovaries and nearby structures. It is a safe and painless procedure frequently performed to assess pelvic pain, abnormal bleeding or questionable pelvic exam.

Transvaginal Ultrasound

This procedure is done to visualize the uterus, ovaries and nearby structures. It is a safe and painless procedure frequently performed to assess pelvic pain, abnormal bleeding or questionable pelvic exam.

Obstetrical Ultrasound

Obstetrical (OB) Ultrasound uses high frequency sound waves to evaluate placental location and condition; and determine fetal age, size, growth and well being. It can be done either by scanning through your abdomen (transabdominal) or by placing the transducer into the vagina (transvaginal). Transvaginal is similar in discomfort to a pelvic exam. The Technologist will determine which technique will give the best images. Frequently, both methods are used.
