An ultrasound uses sound waves to create images of structures in the body.
An ultrasound is used to show details of structures in the abdomen. It can show features like the size and movement of organs, cysts or growths, or fluid collections. An ultrasound of the abdomen is most often done to:
A physical exam may be done. Bodily fluids may also be tested. This can be done with blood or urine tests.
In some cases, the doctor may advise the following:
You will be positioned on a table. A gel will be placed over the area that will be checked. The gel helps the sound waves travel from a wand to your body.
The ultrasound machine has a hand-held wand. The wand is pushed against your skin where the gel has been applied. The wand sends sound waves into your body. The waves bounce off your internal organs and echo back to the wand. The computer can convert echoes into images on a screen. The images on the screen are examined by your doctor. A photograph of them may be taken.
You may be asked to change positions or hold your breath during the exam.
The gel will be cleaned off your abdomen. You will be able to leave after the test is done. You will be able to return to your normal activities.
After the test, call your doctor if the symptoms you had before the test become worse.
In case of an emergency, call for emergency medical services right away.
