What is a Doppler (Carotid) Ultrasound?
Doppler ultrasound is a test that uses sound waves to create images and sounds of your blood flow. This test can detect narrowed or blocked arteries, or blood clots in the veins. It can be done on the neck, legs or arms. A hand-held probe placed against the skin emits sound waves that you cannot hear. The sound waves bounce off the moving blood and echo back to the probe. The echo is translated into an image that appears on a screen. This test involves no radiation and is painless. During a doppler ultrasound, you may hear a "whooshing" noise. This is the sound of your blood flowing. You may also see tracings of your blood flow on a screen. The sonographer can answer your questions about the test, but only a doctor can explain the results.


What is a Pelvic/OB Ultrasound?
Pelvic ultrasound is an imaging test for determining the condition of the organs in the pelvic area, usually the female reproductive organs. It can also help assess pain in the pelvis (lower abdomen). Pregnancy ultrasounds are generally done to determine the size of the fetus and the gestation dates. Ultrasound uses sound waves to form pictures of your organs that appear on a screen. The test is often done by moving a probe over the pelvis. At times, it is also done by placing a probe inside the vagina. This test involves no radiation and is harmless.

What is a Breast Ultrasound?
A breast ultrasound is an imaging test that will help determine the condition of abnormal breast tissues found on a mammogram. Breast ultrasounds are a necessary factor when a lump is found. Breast ultrasounds can determine size and density of a lump and are also beneficial when locating the exact coordinates for such procedures as needle biopsy.

What is an Abdominal Ultrasound?
An abdominal ultrasound is an imaging test that focuses on the organs in the abdomen located between the diaphragm (lower edge of the rib cage) to the belly button. These organs include the liver, gall bladder, spleen, pancreas and more.

What is a Thyroid Ultrasound?
A thyroid ultrasound is an imaging test to determine the condition of the thyroid gland and surrounding tissue.

Before The Exam
Preparing for an ultrasound requires little effort, although some exams (abdominal, pelvic, obstetric) require a specific prep to follow. You may be asked to undress from the waist down, keeping your underwear on. Or, you may be asked to change into a gown. This test most often takes from 30 minutes to 90 minutes. Be sure to allow extra time to check in.
Tell the sonographer if you've had:

• A stroke
  
  
• Symptoms such as short-term loss of strength, speech, vision, numbness or tingling.
  You may be asked about your health. Your answers will help the sonographer tailor the test to your health needs.

 
During The Exam
You will lie down on an exam table. Non-greasy gel will be applied to the area being scanned. The sonographer will then press a hand-held transducer-probe against the area of your body being examined.

Be Aware That

• The gel may feel wet, but don't worry, it won't harm your skin or clothes.
• You may feel pressure. If the test is painful, let the sonographer know.

After The Exam
Before leaving, you may need to wait briefly while your images are being reviewed. You can return to your normal routine right after the test. Your doctor will let you know when the results are ready. 

Test Tips

• Be ready to talk about your overall health. This includes any symptoms you may have.
  
  
• You may have to remove some of your clothing or wear a gown.
