Prior to Test
Description of Test
You will lie on a table. A gel will be put on your belly over your bladder and kidneys. The gel helps the sound waves travel between the machine and your body.
The ultrasound machine has a hand-held instrument called a transducer. It looks like a microphone or wand. The transducer is pushed against your skin where the gel was applied. The transducer sends sound waves into your body. The waves bounce off your internal organs and echo back to the transducer. The echoes are converted into images that are shown on a screen. The images are examined. A photograph of them may be made.
After Test TOP
The gel will be wiped from your belly.
