What is Ultrasound and how does it work?

Ultrasound is high frequency sound waves that are not audible to the human ear. These sound waves can be produced by causing certain types of crystals to vibrate within a probe called a transducer. As the crystals vibrate, the sound waves are transmitted through the body and reflect off of the different structures within the body. The transducer has the ability to receive the reflections (echoes) and transmit them to a computer in the ultrasound machine. The computer then analyzes the echoes and forms an image of the anatomy scanned. The images that are produced can display valuable information for diagnosing and treating a variety of diseases and conditions.

Isn't Ultrasound the test for pregnant women to look at their babies?

Yes, Ultrasound is the test for pregnant women, but this is only one of many reasons that Ultrasound can be utilized. Ultrasound can be used to scan any soft tissue in the body or soft tissue organs in the upper abdomen as well as the lower abdomen (pelvic area). Ultrasound can also be used to look at blood flow in the veins and arteries of the organs and extremities to diagnose clots that can result in blockages of the vessel.

What are the advantages of an Ultrasound compared to a MRI or CT?

Ultrasound has the ability to distinguish between fluid and solid structures. Unlike CT, Ultrasound does not use any radiation for imaging and costs much less then a CT or MRI. Also, Ultrasound does not have to use contrast agents to provide a diagnostic exam. Information from an Ultrasound, CT or MRI compliments each other's findings. Each can provide additional information for your doctor's review and diagnostic capability.

Does Ultrasound use radiation for imaging?

No, Ultrasound does not use any type of radiation. Ultrasound is simply high frequency sound waves that are transmitted through the body when imaged. There are no known documented effects from the use of high frequency sound waves in medical imaging.

What is the prep for Ultrasound?

Ultrasound preps vary according to the type of Ultrasound ordered by your doctor. Contact your AHI center for complete instructions for your exam.

Why do I have to have a full bladder for my Ultrasound?

Ultrasound is used extensively for diagnosing pelvic abnormalities. A full bladder basically provides an excellent window for the sound waves to pass through, thus allowing better visualization of the pelvic anatomy. Not all Ultrasounds require a full bladder. Your doctor or AHI center can provide you with appropriate instructions for your Ultrasound.

Why can I not eat or drink for an Ultrasound?

Not all Ultrasounds require you to be NPO (nothing to eat or drink). Certain abdominal organs are affected by the intake of food or drink and would negatively affect visualization of these organs and result in less than diagnostic information. Consult your doctor or imaging center for complete instructions for your Ultrasound exam.

How long does an Ultrasound take?

Most Ultrasounds require 30 to 60 minutes for completion. As always, problems that may arise will be addressed and managed appropriately.

Can I get the of my Ultrasound from the technologist?

No. While the technologist is trained to perform the Ultrasound, they are not allowed to interpret the Ultrasound. Our board certified radiologists will interpret the results of your exam. Your physician will then provide a diagnosis for you based on these interpretations.

How long does it take for my doctor to get the results of my Ultrasound?

A board certified radiologist will review and interpret your Ultrasound examination upon completion. Your doctor will have a written report within 24 hours.
