What is an Ultrasound?
Diagnostic ultrasound is an established method of diagnostic medical imaging using a high frequency sound wave and the principle of sonar. Because ultrasonic waves cause no damage to human tissues, they are an important tool utilized for both diagnosis and treatment of disease. It is a reliable, cost effective means of evaluating many internal organs, including the liver, pancreas, spleen, kidneys, aorta, gallbladder, ovaries, uterus, prostate, testicles, and thyroid. It is routinely used to evaluate fetal growth and complications of pregnancy. Ultrasound is very patient friendly --there are no injections. Only a small instrument (transducer) will be in touch with the body.
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.


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 our ImageConnection staff 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.
