Ultrasound, or ultrasonography, is a common imaging exam. Unlike X-rays, ultrasound does not expose you to radiation. Instead, it uses painless sound waves to create pictures of the inside of your body.
There are three types of ultrasounds:
- Three-dimensional (3)-D ultrasound shows images similar to what a doctor might see during surgery.
- Conventional ultrasound shows flat images.
- Doppler ultrasound shows blood flow in the arteries, veins, and organs.

Why Doctor Perform Emergency Ultrasound
Ultrasound is an invaluable tool in helping emergency doctors triage and diagnose injuries and illness. In an emergency, ultrasonography can help doctors:
- Examine internal organs and tissues
- Evaluate the causes of symptoms such as pain, swelling, or infection
- Observe blood vessels and blood flow
- Guide procedures such as needle biopsies
- Assess the health and well-being of a developing baby in women with pregnancy-related complaints
What to Expect With Emergency Ultrasound at Dignity Health
During an ultrasound, a technologist guides a small device, called a transducer, over the skin of the examination area. A water-based gel helps the transducer maintain contact with your skin. A radiologist will interpret the results and share them with your emergency room doctor. The results of the ultrasound will help the doctor make a diagnosis and recommend additional testing or treatment.
There are no known risks of ultrasound. However, there is the possibility of a false-positive or false-negative result. A false positive is when the ultrasound is interpreted as showing a problem that isn’t there. A false negative result is when ultrasound misses a problem that is present. The quality and accuracy of an ultrasound depends upon the skill of both the sonographer and the doctor interpreting the images.
Recovery After Ultrasound
Ultrasound typically takes from 30 minutes to an hour. During the exam, you may feel pressure as the transducer moves over your skin. Some types of exams use a probe to see inside the body. Examples are a transvaginal or transrectal ultrasound. You may have some discomfort with these exams.
There is no recovery necessary from the ultrasound itself. You may need additional imaging tests to give your doctor more information or to confirm initial results. Dignity Health provides high-quality emergency services, including emergency ultrasound, in Arizona.
