Ultrasound

Arterial/Vascular Doppler Ultrasound
This test examines the blood flow in the major arteries and veins in the arms and legs with the use of ultrasound (high-frequency sound waves). The test combines Doppler ultrasonography, which uses audio measurements to "hear" and measure the blood flow and duplex ultrasonography, which provides a visual image.

Carotid Doppler Ultrasound
Carotid ultrasound is a test that shows the carotid arteries (vessels in the neck that provide blood flow to the brain), as well as how much blood flows and how fast it travels through them.

Venous Ultrasound
The most common reason for a venous ultrasound exam is to search for blood clots, especially in the veins of the leg. Other reasons include: Finding the cause of long-standing leg swelling, aiding in placement of a needle or catheter in a large interior vein, mapping out the veins in the leg or arm so that segments may be removed and used to bypass an area of disease, and examining a blood vessel graft used for dialysis if it is not working as expected.

Abdominal Ultrasound
Ultrasound imaging is used extensively for evaluating the kidneys, liver, gallbladder, pancreas, spleen and blood vessels of the abdomen.

Echocardiogram
Echocardiogram is a test that uses sound waves to create a moving picture of the heart. The picture is much more detailed than x-ray image and involves no radiation exposure.

Breast Ultrasound
A breast ultrasound is a procedure that uses reflected sound waves to view and produce a picture of the internal structures of the breast. A breast ultrasound can show all areas of the breast, including the area closest to the chest wall, which is hard to study with a mammogram.

Pelvic Ultrasound
A pelvic ultrasound uses sound waves to make a picture of the organs and structures in the lower belly (pelvis). A pelvic ultrasound looks at:

  • In women, the bladder, ovaries, uterus, cervix, and fallopian tubes
  • In men, the bladder, prostate gland, and seminal vesicles

Testicular Ultrasound
A testicular ultrasound (sonogram) is a test that uses reflected sound waves to produce a picture of the testicles and scrotum. An ultrasound can show the long, tightly coiled tube that lies behind each testicle and collects sperm (epididymis) and the tube (vas deferens) that connects the testicles to the prostate gland.

Prostate Ultrasound
A prostate ultrasound is a diagnostic test used to detect potential problems with a man's prostate. An ultrasound test uses very high frequency sound waves that are passed through the body. The pattern of reflected sound waves, or "echoes," shows the outline of the prostate. This test can show whether the prostate is enlarged, and whether an abnormal growth that might be cancer is present.

Renal Ultrasound
Renal ultrasound can be used in the evaluation of a variety of complaints and conditions. These determine the source of abdominal pains, such as kidney stone; help in the evaluation of infection in the kidneys or bladder; help to identify congenital abnormalities (these are abnormalities that you have been born with) of the renal tract; help in the evaluation of problems related to the prostate gland; and help in identifying injuries to the kidneys and bladder after accidents.
