An ultrasound scan is a medical test that uses high-frequency sound waves to capture live images from the inside of your body. It’s also known as sonography.
The technology is similar to that used by sonar and radar, which help the military detect planes and ships. An ultrasound allows your doctor to see problems with organs, vessels, and tissues without needing to make an incision. This type of non-invasive procedure is very helpful when it comes to planning the course of action for your health concerns.

How to prepare for an ultrasound
The steps you will take to prepare for an ultrasound will depend on the area or organ that is being examined.
Your doctor may tell you to fast for eight to 12 hours before your ultrasound, especially if you’re receiving an abdominal ultrasound. Undigested food may block the sound waves, making it difficult for the technician to get a clear picture.
For an examination of the gallbladder, liver, pancreas, or spleen, you may be told to eat a fat-free meal the evening before your test and then to fast until the procedure. However, you can continue to drink water and take any medications as instructed. For other examinations, you may be asked to drink a lot of water and to hold your urine so that your bladder is full and better visualized.
Be sure to tell your doctor about any prescription drugs, over-the-counter medications, or herbal supplements that you take before the exam.
It’s important to follow your doctor’s instructions and ask any questions you may have before the procedure.
