What is an Ultrasound?
An ultrasound scan is also known as a sonogram. This test uses high-frequency sound waves to create detailed, real-time images of the inside of the body and show blood flow. Ultrasound testing is safe and noninvasive and carries no known risks.
Why Do I Need an Ultrasound?
Your doctor may recommend ultrasound to diagnose a wide range of health conditions without using radiation or an invasive procedure. You may have an ultrasound test so your doctor can examine:
- Arms and hands
- Abdominal organs, such as the gallbladder, liver, kidneys, spleen, or pancreas
- Baby’s health and growth during pregnancy
- Breast tissue, especially to check for breast cancer after unusual mammogram results
- Legs and feet
- Pelvic area
How to Prepare
Ask our staff how to get ready, and read the following instructions for your specific test:
What to Expect
A friendly, certified technician will focus on your well-being, comfort, and safety while performing your ultrasound.
During the test, you’ll lie on an exam table. You may need to remove some clothing or change into a hospital gown.
Your technician will apply a water-based gel to the area of the body the test will examine. Then, they’ll gently press a device called a transducer against the skin. This device sends sound waves into the body while your technician moves it along the skin at various angles.
How Long Will It Take?
Most ultrasounds last 30 to 45 minutes.
Results
A radiologist will review your images and send a report to your doctor who ordered the test. Expect a phone call from your doctor’s office to discuss the results and next steps.
