Ultrasound imaging, also known as ultrasound scanning or sonography, is a method of obtaining images from inside the human body through the use of high frequency sound waves. The sound waves’ echoes are displayed as a real-time, visual image. No ionizing radiation is involved in ultrasound imaging. The technology is similar to that used by sonar and radar. Since ultrasound uses no radiation, it’s the preferred method for viewing a developing fetus during pregnancy.
An ultrasound can provide a non-invasive view of the gallbladder, pancreas, thyroid, and testicles as well as other organs in the body. Sonography is also utilized to guide surgeons’ movements during biopsies or other medical procedures.
What should I wear?
You should wear loose comfortable clothing.
What can I expect?
A technologist will explain the test, duration and ask about your medical history. It is possible you will be asked to change into a gown or remove clothing. You will then be instructed to lie on a hospital stretcher. The sonographer will use a probe or transducer and some cool gel on the specific body part to visualize pertinent anatomy. The typical duration of ultrasound testing is 30-60 minutes.
How do I prepare for my exam?
Preparations are exam dependent and you will be contacted with instructions the day prior to your testing.
Can I take prescribed medication?
